Violence. It will not resolve the crisis. Violence and blood she had bloodshed must stop immediately. Police arrest the leader of the opposition. The fact is, we have four dead americans. This is a comeback story. A story of how she went from pretty well in thest of the American Public back to a high point. Okay. We begin tonight with out break of violence in ukraine, 20 people were reported killed tuesday in clashes between police and protesters in the countrys capital kiev. Hundreds more may have been hurt. The violence started earlier in the day after protesters reoccupied city hall and marched in to an area near Independence Square where police had amassed. Police are accused of using live ammunition as well as tear gas, Water Cannons and rubber bullets to fight the protesters. Ukraine has been paralyzed by political turmoil when the president reject aid deal with the European Union in return for financial sport and closer ties with russia. For more i am joined from ukraines capital kiev by natialia correspondence with an independent online news seven theres in ukraine. Thank you for doing this for us. Where have you been today . And what did you see . Reporter we have been following as editor, anchorrer and journalist everything happening from early more than generally. So far i have a shift in the newsroom. But i should explain whats happening now. Its most urgent. We are now doing our news and talking to all the reporters from the field. So what is is new, what we havent heard is that its also the thugs in plain cloths have joined the police and still a huge out break of violence in the independence scare. The crack down is in full force and people try to protect themselves. The protesters, with different kind of means, we know that also there are injuries from both sides. Buttethe difference of the two events is definitely during the day there was a clash and we can talk about the use of force some legitimate use of force and the live ammunition and it is confirmed, i have we have a journalist who brought the bullet in to the studio and its not just rubber bullets but life. Now the situation is going on, and i guess for the last more than five hours, there is a constant call from the people and from the position and all International Body to his stop the violence that would do something that the police and this force would stop the crack down because little by little they overtaking the square, which actually was put on fire. And, yes, now the cocktail molotovs are use but also the live ammunition as well. But the people in the square dont know its kind of an asylum for them. Its their camp and the biggest concern is since the early days there are a lot of injured. And we are talking about hundreds of people. Hundreds of injured. And because of the violence in the place, really the ambulances its hard for the people to get the injured and get some help because we continue know how many people are missing since the day. And its happening right now, there are some development in the country, but the only response from the government is this entire terror operation which in ukraine is unique, we have never heard of the word terror here, thats probably the main thing to address. Well, it is scary to of what the pictures of the violence and doesnt surprise me at all seeing those pictures that it must be hundreds of people who got hurt. Now, who started the violence today . Is it clear that it was the police and not the protesters . Yes, in a way we know what was happening i wont get in to the politics, because of course there was this idea of the attempt of the position to put up the alltime constitution which would have a less give less power to the president. When the people marched to parliament there were people in plain clothes also throwing stones, the people also thrown stones but got the answers with the rubber bullets, with the grenades, what is really happening is that the subway first time in the ukrainian history was shutdown in order that more people wont come to the center. So the center is somehow cut for the people, people cant go there, but i know a lot of people are walking to reach the place because thats the only there is not any trust in the no trust in any you know, any police or anybody. So there should be just volunteers or who would help the people, and also there are a lot of volunteers among the doctors and there is also people who are in the center, they, for instance, are afraid if they would be taken to the hospital, they would being arrested in the hospital. Because these cases were also forwarded. But of more concern there is one person, the president who doesnt pick up the phone, from the president of the European Commission from angela merkel, joe biden more or less reached him. But seems that all day there was not any sign and this is the only person can somehow gifford to stop. Is there any chance that yanukovych will back down a little bit. There are reports that hes meeting with Opposition Leader vitale klischko. Is it possible ideal will be reached and this will calm down . There is just a hope, because so far there is a feeling that the red line is kind of crossed. Because the government also used these people with unknown definition, who also attack and and really, for with every hour there are more people injured. So the hope is there, but but the answer is not there. We hope for the sake of all the people who have gotten hurt that something i should explain, i am sorry for interrupting. Its very important, for the International Audience to understand, this is something which happened first time in the ukrainian history. Never. There was a case a month ago when the three people died and the first people died in the clashes with police in ukrainian history. We have never seen Something Like that, this is why the people are very confused. They are disturb ed they dont know what to do they are disturbed and society is not ready for this. I believe the danger is that people are ready to answer because so far they didnt see any concession from the government. Its very disturb to go watch this. Thank you very much for joining us telling us whats going on in kiev. Switching topics to another nation in crisis, venezuela Opposition Leader low polled owe lopez vend today police in caracas tuesday but not before telling a huge crowd that he wasnt afraid to go to jail to highlight what he called the countrys corruption and did he line after 15 years of socialist government. Lopez also said imprisonment would be well worth it if it woke up the venezuelan people to the countrys polite. After the arrest, 10s of thousands of demonstrators blocked the streets in say show of support for lopez and against the government. It has been racked by december straighters for weeks by people saying they have had enough of crumbs, shortage of basic items and inflation thats the worlds highest despite being an oilrich country. Meanwhile the president told supporters that lopez must answer for what he called treason us acts. Earlier protests left three people dead so he faces channel of homicide. I am joined by venezuelas ambassador to the u. N. , president of the u. N. Council and government of caracas, its great to have with you with us, we saw in the streets of caracas yourself today. You were out there speaking to the soldiers from the National Guard blocking a street. You went right up to them and talks to them what did you say . I was telling them, more to the officers behind them that they were not only obstructing a peaceful demonstration, but but they were threatening and abusing the rights. Venezuelan people. I told the officers one day you will be judged and prosecuted almost as war criminals because thats the way the national venezuela. Did you get any kind of response from them . No. The officer said keep cool. The officers knew me they knew i wont going to stop. It was a way to demonstrate reaction to the armed firsts in venezuela to abuse the rights and demonstrations like today. You are one of the major Opposition Leader, low owe peeled owe lopez who has been the inspiration or one of the inspirations had been in hiding after the president said he was going to be ate ared was it the right move for him to surrender to president maduros forces . Its such is a personal decision to do it. He wanted to demonstrate thats not an outlaw. We dont have a judicial system. There are no laws in venezuela that will treat him objectively. But the regime relies that putting lopez in jail, lee polled owe lopez will generate a lot of problems. What started 13 days ago are student december strayings against Human Rights Violations throughout venezuela is blooming and grown for nba to a massive protest which i believe will increase in the forthcoming days. Its also being reported that another leader of lopezs party is now being order today surrender. Are they going to be going after more and more Political Prisoners and can they get fair trials . You just said the judiciary is just not independent. You know, we have been living here for 15 years the same system. Many of the venezuelan leadership and opposition have not realized that we are facing to begin with a military government because venezuela is a military regime, controlled by the cuban amazingly, by the cuban regime. And as such the cubans have great experience in exercising pressure and nba how to pressure societies. And they are doing that in venezuela, they control the military, they control the police, they control the intelligence agencies, so they are in full control today in venezuela. Even though thats the situation we give them 100,000barrels of oil a day. This began with hugo chavezs close relationship with fidel castro. But chavez was elected a number of times, maduro last year, very, very tight, almost split down the middle vote, but they also won elections in december. So what do you and other members. Government . You know, actually, when chavez died, venezuela entered into a transition process which i believe has been now coming to an end with maduro. You know, to begin with, the last president ial elections, we won the last president ial elections, actually, we were not able to gain rick mission of that. But its a fact. And in the election we won the big cities. But there is no electoral option for venezuela. We win all the elections the regime will not allow United States to gets to power. We have 60,000 cubans in venezuela, we have all kind of narc owe traffickers, mafias, under the protection of the government. Seven generals of the highest rank which are on the kingpin list of the United States treasury. Never not going to give up 90 billion a year which is the income of venezuela a year, we are a great business for the cubans the mafia groups and the corrupt military officers and the corrupt members of the high arc i of venezuela. There is a great appetite to preserve it as we have it. Maduro said to us last week, i dont care youll never get back to power. If i let loose all of these civilian groups, they have a lot of gangs which are armed, today they did not exhibit they want because there were a lot of journalists in venezuela. But they have these gangs, which are criminal gangs, which last week killed three young people. And this afternoon today, they shot another girl, a queen beauty of valencia, was shot in the head. So they use these groupings in order to not to let the armed forces because the armed forces are beginning to get very concerned about implications of the responsibilities that they may face in the future regarding of crimes that have been committed for so many years. And we have seen pictures. Opposition rallying in caracas and rallying around the country. But there is tremendous censorship; there not . Its very hard to get much of this out because the government controls almost all of the media media. You know, the control that they have is about 90 but they have 100 percent because whenever they want, the president enters what we call the chain, the link, all the televisions and radio stations they change them to one voice and one view. And chavez exploited that a lot. Now this gentlemen, by the way, we dont even know whether the gentlemen who acts as head of venezuela is a columbian . , he has never been able to prove document that hes a venezuelan citizen. The people watch this program, antonio maybe wondering what kind of country we are, what kind of country we have become. Venezuela for such a long time a respected member of the international community. Today we have become the source of financing for some of the worst causes against humanity. We were friend with qaddafi. Castro, you choose them. If there is an enemy of the United States then immediately the government of venezuela joins the ranks. Now, and u. S. Diplomats have been thrown out of venezuela, the u. S. , insists the charges that the u. S. Has been involved in all of this are false. And baseless and that venture swa is la is trying to distract from of actions, although the u. S. Does support some opposition groupings. Its very good to have you on the show and we appreciate you joining us. Thank you very much. Thank you so much. We have we break we want to bring you the latest from another country convulsed by previous test on his tuesday.

With Marijuana Legalization on the rise, concerns about the safety and prevalence of driving after smoking pot are growing throughout the country. But the issue of driving under the influence of marijuana is complicated from how to measure impairment to knowing just how impaired they are when high. Joining us from colorado is glen davis the Highway Safety manager of the Colorado Department of transportation. Good to have you with us. According to american journal of epidemiology, the number of car Crash Victims with pot in their systemses increased threefold from 199 to 2010. Do you believe marijuana is to blame . I believe that shows that marijuana certainly is a substance being used and is a contributor to those crashes. According to another study a 20yearold drunk driver is much more likely to be in a fatal crash than i think its almost 20 times more likely than someone who wasnt drinking at 20. Driving while high doesnt seem to have as nearly as much of an effect is driving after having used marijuana less dangerous than drunk driving . I dont think so. Marijuana is an impairing substance just like alcohol. And if pima beus it or even just use it to the point of impairment, its equally dangerous. How reliable or how do you enforce it. Other studies show that as little as 30 of people that smoked marijuana fail the test. How do you figure out who is impaired and who is not . I can speak for colorado which we have Law Enforcement officers highly trained in detecting impaired drivers whether its alcohol or drugs. Its not just the roadside that determines the arrest. Its the persons driving, what it was like during their contact, the type of violation it was, the innin indicia of impairment that the officer sees. The test doesnt determine if they were under drugs it determines if they were impaired and need to be arrested for further testing. Are there marijuanaspecific tests . Because, again, if that study found that about 30 of people smoked marijuana, can do the standard field sobriety test, it would seem that you might not be able to just checking them casually and the roadside test will be able for figure out whether they are high or not . The roadside tests of standardized and should be able to detect if someone is impaired. In colorado if someone is arrested and the officer feels there is a likelihood that the impairment is something other than alcohol, he can call in a drug recognition expert. The drug recognition expert can do some other tests on a person, they are not really at road roas more in a clinical situation, like in a processing room and then he can that dre can make determination fist that person is impaired by something other than alcohol or a combination of drugs and alcohol. You know you have done phone surveys that people dont know that dui laws apply for marijuana. But colorado treats driving under the influence of marijuana as the same as alcohol, is that the right approach . Thats direct. In colorado the statute for dui, its alcohol and or drugs. So it could be a combination of alcohol, drugs, or just alcohol or drugs, but just the fact that marijuana was legalized in colorado it it was really no change for the dui statute. Driving while impaired by marijuana or any drug has always been illegal. Now, colorado has some legal that fresh holds for marijuana, one of the issues that arises when you read about all of this is that people have different tolerances and that marijuana stays in peoples systems. So a heavy user can actually still have pretty high levels of the active ingredient marijuana in their system days after the last time they smoked. Well, colorado, what people are tested on is blood. And the blood will show the active ingredient. The ingredient, impairing ingredient which is delta nine tetra knapp
