Four men held without charge at the Guantanamo BayDetention Center have been released and returned to afghanistan. We begin with a story developing. Two new York City Police officers were shot and killed in what some described as an execution style murder. The Police Commissioner called it an assassination. The officers were in their patrol car in brooklyn, eating, a gunman walked up and opened. He is oiled as ismail brindley. After the shooting he ran into a subway station and shot himself in the head. He was pronounced dead at the scene. According to witness statements the suspect has been identified as 28yearold Ismail Brinsley walked up to the police car. He took a shooting stance on the passenger side and fired the weapon, his weapon, several times through the front passenger window, striking both officers in the head. The officers never had the opportunity to draw their weapons. They may never have actually seen their assailant, their murderer. Approximately 5 45 this morning and baltimore, maryland, a female, believed to be brinsleys former girlfriend was shot and seriously wounded at her residents. Information was received from the victims mother that brynsly was posting on the victims instagram account. He may have had associations with the east flashpoint area of brooklyn. 2 45 this afternoon baltimore authorities sent a fax to the n. Y. P. D. And other agencies. Tragically, this was essentially at the same time as our officers were being ambushed and murdered by brynsly. Officers were shot execution style, particularly despicable actinsley. Officers were shot execution style, particularly despicable act which goes at the heart of our society and democracy. When a Police Officer is murdered it tears at the heart of our society. Reaction from brooklyn has been outrage, many calling it senseless. Its Unacceptable Behaviour to go and shoot anyone, Police Officers in their car having a meal. Do we live in gods city. It doesnt happen like this. This is a difficult time for n. Y. P. D. Its been since 2011 since losing a Police Officer in the line of duty. The information is coming in. In a press conference, mayor bill de blasio and police chief were measured. Lets go through what we know. It apparently went back to baltimore. What do we know . He shot and killed his girlfriend. That was mentioned and what the Police Commissioner bill bratton said is when the Phil Baltisberger p. D. Put out the baltimore p. D. Put out the flyer, a wanted poster, it happened almost simultaneously. They were killed so quickly they were unable to draw guns. They were in a vehicle in a car outside a Public Housing market, a place they sit to patrol the area and the man came up and shot them both, hitting them both in the head. Which is why they are using words like assassination and execution, and you have to be deliberate to use the words. Lets talk about how Police Tracked him to new york. The young woman, the mother said if you look at the instagram posting, it made mentions of new york. Social media will be an ongoing investigation. Something was mentioned on twitter. He may have taken over her account. We know in a chilling testimony, that the Police Commissioner gave us explicit detail of how this went down. Well hear more about that. Lets dip into the press conference. At this early stage we dont see a linkage to terrorism or a radical group. Thats what the investigation hopes to determine, if this person had access to social media accounts we have not encountered that yet, as of four hours ago. Thank you everybody. When something this horrific happens in new york, the question of terrorism comes up. If im not mistaken, i believe the commissioner was asked that question more than once. He used strong language, assassinations, murder. Theres nothing murky about that. They are not looking into terrorism attack. They did not use that word. It was more of an assassination, coldblooded murder of two of n. Y. P. D. s finers. And social media will be part of the investigation. Tell us the officers names, whose families have been changed. We dont know their ages, they are young. Wen jen lu and his partner. Seated in the front of of their vehicle. The beginning of a lengthy investigation. The person responsible killed himself, they are not able to question him. Therell be a lengthy investigation to figure out what led to this and two families three, lets not forget the woman shot in baltimore changed more ever. Stay on this, well check in shortly. Also in miami protesters in the streets of Little Havana to voice opposition to president obamas new policy to cuba. It was a small process as raul castro directed his National Assembly in cuba. Praising president obama for the communist shift and warning change will not come easily. Translation our people must understand that the announced changes will require a long and hard fight requiring the participation of International Community and american society. The cuban leader welcomed the new embrace, promising to defend the countrys ideology. This report from havana. This was a highly anticipated speech by the cuban president. Its the second time we heard from him since the announcement on wednesday. He said that while this will be a relationship between two equals, cuba and the United States he said that any change here in cuba would happen on cubas terms, and nobody elses. That was indicating that he planned to keep the respect of the people, and the Decision Making of how cuba decides to carry on diplomatic, economic changes in the future. He really was reaching out and saying looking for respect. It was a speech for an international audience. Throwing a little bit of cold water on the rapid change speculation on the island. It will take time. We cant pretend that by improving ties in the United States that it will shaken what cubans have fought for centuries. The president brought up the issue of coupan american Cuban American Community in the United States. Especially those primarily in florida. Saying they may try to sabotage the process going forward. Clearly theres certainly a lot of no love loss between that group and a lot of cuban leadership here. Therell be a lot of opposition in u. N. Congress. Here is what raul castro had to say about that today. Translation we do not ignore the criticisms that president obama had to endure by forces opposed to the normalization of relations to cuba, including legislators of cuban origin. On the streets and over cuba i can tell you that there is still a lot of anticipation of what this change really is going to mean. After a few days now people on the streets are thinking about where does this actually go from here. I think raul castros address to the nation was mostly meant to remind cubans that this very much is a country where change comes slowly, nevertheless, there is an air of optimism and excitement that is building about how this new relationship between the u. S. And cuba can have benefits for many cuban people on the ground in this island nation. Cuban american politicians in miami say the restoring of relations in koubee is an cuba is an outright mistake. The starving of the nation is the blame of the castro brothers. Im tired of this administration sitting at the table with our worse enemies, apologising for the kates. Cuban americans are divided. A poll published showed 60 of cuban americans oppose removing cuban from the state terrorism list. 50 1. 8 million americans stay tuned well have more on the shift in diplomacy between the u. S. And cuba in the deeper look segment in a few minutes four detainees have been released from Guantanamo BayDetention Center. The four men were returned to their home country of afghanistan. They were held at guantanamo over a decade over their alleged ties. The lawyers argue the claims could not be substantiated. They are expected to be reunited with their families in the future. A tunisian man who spent 13 years locked up was released and told al jazeera he never doubted that he would be released eventually. I have learnt a lot from my experience in guantanamo. I was vouched by lies much everyone was lying from lawyers to integrators to guards. We became hard wired not to believe anyone. I no longer believe anything unless i see it. I did not believe i would be coming here until i landed and left the plane. I expected they changed their mind at any point when i was on board. As a muslim i have deep faith in god. That is why im not worried about the future. I served 13 years in guantanamo for better and for worse. According to the Human Rights Group reprieve, the u. S. Acknowledged holding 779 people at the camp to date. There are 132 detainees left at Guantanamo Bay. Thats the lowest number since the prison opened in 2002. 63 of them are cleared for release. U. S. Authorities say they cant send them home because of security concerns or the home countries are unwilling to take them back. 52 countries accepted guantanamo detainees, 10 were transferred to unnamed locations. I spoke to Ltcol Barry Winn guard and i asked what is next for the others released. Once the men return home, theyll be released forth with to their families, and not have to serve additional time in gaol. Its important to point out that abdo ghani, my client, as cleared for release since 2009. The unfortunate thing is that even being cleared. He had to languish in Guantanamo Bay, an additional four years. His mother died during that time, unfortunately. We welcome what the president obama duration has done, but we hope it would be sped up in a way that more me can do the same as ab du ghani did. Its a long amount of time and a lot changes over the course of 10 years. Families are different. Its the first return of prisoners to a wartorn country like afghanistan since 2009. Why the change now . As the United States winds down hostilities, and afghanistan the just ifghts for holding the men in Guantanamo Bay seems to be waning. The sfat us in which they were held seems to terminate after the cessation of hostilities. American soldiers return home. I think that is one big part, and i think another is that we have established that allegations against our client was wrong in many ways, and the United States agreed with us, acknowledging that they couldnt proceed in a courtroom in the United States. Ltcol barry win guard there. Coming up, the shift in u. S. Relations drawing prays and criticism from u. S. Americans. A deeper look at that next. Things are starting tomorrow. The beginning of winter, we have storms moving in, dumping a lot of snow in a few places right when a lot of people will be travelling. Details in the forecast coming up. Welcome back. Tonight we take a look at americas new relationship with kooub a. The ties between cuba and the rest of the world is normal. Its a shift in foreign policy. It will ease the trade in the embargo in havana. Polls show cuban americans show the president s plan. Andy gallagher has more on the divide. [ singing ] reporter in the cuban neighbourhood,business as usual, eighth street is a popular destination for the worlds tourists. Eric otiero moved to miami when he was three years old. His sister and grandparents remain on the island. They sent four times as much money. They are concerned with bigger issues. What else do they speak freely, do they have their culture, their own life. You cant say what you think, what you aspire to or own your own home, unless you have an american family. Nothing will happen. Across town in the heavily cuban neighbourhood, its the subject of the debate. The man that owns the cafe says his customers have opposing views that he sees old friends fall out. People have been eating breakfast and lunch together side by side, it felt a little heated and anyone that talks to each other by the time breakfast or lunch was over. Amongst the younger generation, changes were viewed differently. Campaign groups fought for closer ties and claimed the majority of cuban americans welcomed a new approach. By and large the changes, the changes in our policy, so that we increase the flow of contacts and resources to the cuban people is favourable. Normalizing relations with cuba was never going to be an easy transition, especially the older generation. The demographic changes led to new opinions, and an acceptance that change may be worth a chance. This is the biggest shift in u. S. Policy towards cuba in half a sentry. Its a deeply divisive issue. Many dont want to accept change, others are waiting and hoping to see what the future might bring. To discuss this further, lets bring in the professor of black and latino studies, and eric, professor of history, director at the center for national studies. I thank both of you. Professor, starting with you, you are with me. Why now . Why now . If president obama had his way, he would have done this a while ago. In 2009, alan gross was arrested in havana, and spent the last five years in prison, and that was an obstacle between the two governments. Now, we had an election that the democrats lost handily, and i think obama doesnt have anything to lose, hes thinking about his legacy. Finally in his speech, its the right thing to do and there has been a lot of things happening in cuba for the last five years, economic changes have been happening on the island. And this is a way to encourage those, capitalize on them, reaching out to people, entrepreneu entrepreneurs. Well talk about the economics of it. Professor, do you agree with some of those reasons . Yes. I think that this is a surrender of the cuban government to new Political Economic facts, and i think the most important thing is the one of the many things thats occurring as a result of a drop in the price of oil. Venezuela was giving cuba oil at low prices which they were reselling. Cubans saw the writing on the wall. Venezuelas economy is a mess, theres no way they could support cuba, and the cubans decided to cut their losses and make the deal with the United States. Thats really the way i see it. Do you think this weekend is the cuban government. Senator marco rubio says it is a myth that it will help cubans, it will be manipulated by the regime to maintain their power. Of course it will be manipulated by the cuban regime to maintain power. Thats what they want. I dont think theyll necessarily accomplish that. None of us know the future. One thing we know is the past, and embargo has not worked. Why not try something else. In terms of through theling the cuban economy, it already you know, in a sense, that was already tried and didnt work out when the u. S. S. R failed in 1981 and cuba went through a special period. The regime did not crumble at that point. It gave them reason to repress even more, so i dont see that that that keeping the embargo up was really something that would be positive for the cuban people. We want to talk about the cuban people, the cuban americans, they are leaning more towards not approving this. Theres cubans. Who is actually going to benefit from this. Will it be the cuban people, or will it be big business . Right. First i would say that i think the Cuban American Community leaps slightly the other day. The recent polls of last year. Youll flip. Now that obama has done it, maybe people i dont know, i think they are split. Its a generational split. If i can get in there. Absolutely. Theres a generational split. They were pointing out the splits in miami. Theres now cuban american groups that think that the way to change cuba is through principled engagement because, as eric said, the isolationist approach, and as president obama said in his speech, it has not worked. In cuba, how will it effect the cuban people . I think the government we saw was doing a cheerleading thing like we won, and castro saying hey, we are not changing our system, but well have a respectful relationship. We have to keep our eye on the ball, the cuban people, and that was the justification that president obama used. How will the kooub scrn people cuban people be affected. In a number of ways. Imagine when at t gets the ability from the u. S. Government to offer data plans. Other companies can sell cellphones to cubans. The onus is on the cuban government to say well work with you and expand broadband, or itll have to carry the burden of being the obstacle against its own people. Another is entrepreneurial shop. I published a book. Theres 150,000 to half a million of entrepreneurs in cuba. Many need imports, they need to fund their businesses, need investment. If you have a bed and breakfast you need mattresses and food. It could come from the United States, and empower those people. If you can get in here for a moment, basically that the professor things business will be flocking to cuba. Do you agree. Do you think some businesses will be hesitant . Well, this is businesses will be hes it tant as long as cuba is designated a sponsor of terrorism. That creates many financial, you know paperwork requirements and things like that. Until that is lifted, which is something president obama promised to look at. Nothing will change. Its a lengthy process to normalize relationships this relationship with cuba, its a process. Right. Absolutely. And i think you are right there. We can talk about what will happen. We dont know. And its a process and i think its a process that both the United States and certainly cuba, and the cuban government will try to manage very, very carefully to get the maximum advantage each party. Hopefully in the end that will go down to the benefit of the cuban people. The one thing that i think is important to point out as well is that the cuban government has been able to get away with economic mismanagement with all kinds of things, saying its the fault of t
