Then matt began drinking after breaking into a cabin sweat says he became so upset they split up. In the final day, sweat pushed ahead getting closer to canada after hearing matt was killed. The former fugitive now recovering from two gunshot wounds to his torso at a lockdown. The director says inside two guards watch each patient and inmates are often shackled in their hospital beds. How confident do we feel this patient is not going to escape from the hospital . I feel very confident. Reporter and of the many changes at clinton, one is periodic inspections daily of the catwalk area. Mikaela . Jean thank you so much. A seventh shark attack in the last few weeks being reported in North Carolina. This time the 68yearold man in waistdeep water injured and is in the hospital. So what is behind the sudden spike in shark attacks at crowded beaches . We are live in North Carolina with the very latest. Salina . Reporter Officials Say the man was alert and talking to First Responders even though he suffered severe puncture wounds from the hip area down to his knee as well as bites on his calf. That attack happened north of here in the outer banks. Its the seventh to take place off the North Carolina coast in the past month. The victims of the other attacks include a 13yearold girl and a 16yearold boy. Each of them lost an arm. All right. Thats alina down on the coast right now talking about the shark attacks. I understand about ten in the carolinas this year already. Normally they get an average of six so there is an uptick. One of the reasons could be more people in the water right now. But they are watching that very closely. Other news this morning all over the United States officials are warning of a potential july fourth terror threat. Security being stepped up over this Holiday Weekend as isis called on supporters to carry out new attacks. Cnns justice correspondent pamela brown is here with that. Reporter theres more concern this fourth of july among counterterrorism officials and heres why. The symbolling holiday falls during the same time as ramadan and they are encouraging supporters to launch attacks during this time and be awarded even more. Also Officials Say that isis has a major impact on social media. That was not the case the last fourth of july to this extent. Its also becoming harder to detect attacks before they happen. And adding to concern are these near simultaneous terror attacks around the globe that happened the past few days. Many Police Departments are stepping up security across the country. And the nypd says it has the most complex counterterrorism plan in place ever. Heres what john miller had to say about that. They are following the isis call. And the isis call as well as that of other terror groups has been to use what you have on hand. And that means if you can make ament bo youre a bomber. But if you cant, use a gun. And if you cant find a gun, heres a knife. And if you cant find a knife, use a car. Reporter so in light of that concern, nypd in particular says it will have more Radiation Detection devices, more bombsniffing dogs. Also it will be activated, utilizing more than 7,000 closed circuit cameras across the city. Just to put this in perspective, the fbi is watching hundreds of people who could be isis supporters. And just this year so far six months in 49 people have been arrested across the United States on isisrelated charges. The numbers are staggering. Thank you so much for that. Another story to tell you about, several major u. S. Airlines targeted in a federal investigation. The Justice Department wants to know if they conspired to keep their planes packed and prices high. What are you learning renae . Reporter we can confirm that united american and Southwest Airlines have received demand letters from the of justice. The feds are asking for documents and communication that is could prove they Work Together to manipulate capacity of flights. In other words, limit available seats, keeping planes full and ticket prices high. Right now four Major Airlines control 80 of the market and that concerns lawmakers like Richard Blumenthal who is the one who asked the doj to investigate after learning about Public CommentsAirline Executives made. Blumenthal says they suggest industry collaboration. In his own words he says quote, what airlines publicly call discipline is a fancy term for con training the flights available to consumers and raising prices and profits which should be the investigations sharp focus. Now the airlines we have heard from they all plan to cooperate with the investigation. But this allegation alone is really a bitter pill for passengers. Together airlines saved billions on fuel. They are seeing record profit but airfare remains high according to government data. The average price of a roundtrip ticket increased roughly 16. 5 from 2010 to 2014. And we have all felt it. Anybody that has been in the traveling public we have certainly felt it in the wallet. Thank you so much for that. We turn now to the debt crisis in greece.

The american official tells reuters diplomatic talks are in early stages. This first step was reportedly taken by nicholas midermo in march. The u. S. And cuba both announced yesterday they plan to open embassies in each others capitals. Two months after the death of freddie gray the Baltimore Police department talks about installing cameras in police vans. He received an injury in the back of a police van and died a few days later. In the meantime the First Official arrest is taking place in the baltimore riots. An arrest is taking place in the burglary of this cvs store. And look at this pair in the middle of a rushing river after their inner tube got stuck in a rock. Rescuers were able to drop a life vest down to the boy who was eventually pulled to safety. Neither was hurt amazingly. Oh my gosh Incredible Technology being used live there. Meanwhile, back to the lead story, investigators are taking a closer look at the Clinton Correctional Facility in upstate new york where security concerns were they ignored before the two prisoners made their escape . Joining us is dennis bacco, thank you for being here. Good morning. Thank you for having me. Its a pleasure. I want to start off by showing you and our viewers the changes that today are being implemented at Clinton Correctional Facility as a result of all of this. New things will be happening. For instance now in terms of what is going to happen in the cells, Correctional Officers will make weekly cell integrity inspections. That means like checking to make sure theres no hole in the wall a prisoner can climb through. Next they will triple the random cell searches. Random prisoners wont know when it is happening and triple the number they are doing. Number three, unpredictable nightly bed checks. That makes sense. Prisoners shouldnt know to expect the guards every night at 11 00 p. M. Why werent these happening before today . Well, you have to understand that the department of corrections, which is a state agency sets these policies sets these parameters and pushing the guidelines out to the field to the various correctional facilities. So the Corrections Officers in each facility are reacting to department of corrections policies and procedures. Sure enough. So why wasnt the department of corrections doing this until now . Well, look the thing that we constantly have to keep in focus is that these facilities are very dangerous facilities. Assaults are up even though prison population is down by over 20,000 over the last ten years. Assaults are up at a pace for record setting in 2015. These are still very dangerous places mostly because the people that remain even though the population is down by 20,000 many of those that remain are the most violent. So the policies have been designed in the past to try to control the population so that the population is under control, which is why, for instance you have the outer block. That was not a reflection of how the inmates reacted on the outside. The outer block was incentive to get them to act appropriately on the inside. Now the department has decided to change the policies. The Correctional Officers that i represent are very happy to see this. These are hard working men and women who are an i didntntegral part of Law Enforcement and their safety is on the way and they embrace these changes. No one doubts they have a dangerous and important job, if but im interested that you see a dangerous population inside the prison. Do the Correctional Officers do what they can individually also to control the population . Do they . And we just heard from a past correctional officer who said sometimes they will give an inmate a sandwich to make sure the inmate has tv privileges if they think they can get something, like information out of that inmate in order to keep the peace. Well, exactly. We have to keep in mind the relationships behind the prison walls are not real or geneuine. So the inmates are playing the staff, we saw that in the context of Joyce Mitchell who was played by the two inmates, much to their detriment and now hers. But that went both ways the Correctional Officers in order to keep peace and control and to trade information, for instance they will give a sandwich to an inmate if the inmate is willing to be able to provide information about contraband in the facility. So theres a variety of techniques that are employed. But all of it is designed to maintain order in the facility and to keep the Correctional Officers safe. And let me show you a couple other security measures that as of today are going into place. The honor block that you just mentioned will be suspended. It is now under review whether they should have an honor block. Monthly tunnel checks. Previously those happened twice a year. And there will be an executive who reviews inmate counting at every shift. Do you think that these things will make a significant difference . Absolutely. Quite frankly, the Correctional Officers have been long in favor of the imposed changes. Again, we have to keep in mind this is not a statement trying to scapegoat anybody. I think theres no time for scapegoating. Scapegoating we have to fix this problem and get to the bottom of what happened here. And the Correctional Officers want to be an integral part of fixing the problem. They want a seat at the table to help reform the system and come up with procedures such as the procedures that were talking about here this morning that will make them safer and make the facilities more secure. The do you think that gene palmer now charged with aiding and abetting the prisoners for getting out, do you think that he will be convicted . Oh i dont know. I mean it is way too early to say. I think its important to find out however that david sweat, although i heard the early reports, theres question to whether hes believable or not, and thats a healthy skepticism but even he told investigators that palmer didnt have a direct role in the escape. So i think theres a lot more facts that need to be developed, a lot more information that is going to come to light. And it is way too early to speculate on what the outcome will be. Okay, dennis vavvcco, thank you for being on the show. Is there more reason to be concerned this year on july fourth than in the past . Well take a look. This summer, challenge your preconceptions and experience a cadillac for yourself. Take advantage of our summer offers. The 2015 cadillac ats, the sharper performance sedan. Lease this from around 269 per month. At book club they were asking me what youre doing now, janice. Blogging. Your blog is just pictures of you in the mirror. Its called a fashion blog todd. Well, ive been helping people save money with progressives discounts. Flo, can you get janice a job . [ laughs ] you shouldve stuck to softball i was so much better at softball than janice, dad. Wheres your wife, todd . Vacation. Discounts like homeowners multipolicy i got a discount on this ham. Ive got the meat sweats. This is good ham, diane. Paperless discounts give it a rest, flo. All yeah, flo, give it a rest. The threat of an attack from isis have supporters in the u. S. Increasing security for the july fourth holiday to unprecedented levels. Police in new york and los angeles laying out tactical plans to keep fireworks and other festivities safe. Why is the isis threat different than what we have seen in the past . And how concerned should we be . Tom fuentes is our cnn Law Enforcement analyst and former fbi assistant director. We came to you for the goods, my friend. Because i think none of you want to be afraid, we dont want to live in fear because as they say, then the terrorists win, but why so much concern right now, tom . I think the biggest problem they have now is that you know years ago with al qaeda and al qaeda central, you had a more tightly controlled system of generating attacks around the world, if you will. There was more micromanagement from overseas which then enabled tracking from overseas intercepting phone calls, messages and tracking international financing. But now you dont have that. You have isis central putting out these messages to everybody and all the ships at sea to kill to do an attack and you dont have to be coordinated. You dont need permission. You dont have to communicate back and forth. All you have to do is do it. We are seeing the communication back and forth when they are setting up logistics to travel to syria, lets say to join isis. But for the individuals that are here that become radicalized, they dont need anything more. All they need to do is go online and order hunting knives or if they can get a gun or figure out how to make a Pressure Cooker bomb wonderful for them. But they can use a knife, like i said a ratchet, a car, anything at their disposal to kill people. And if they kill one person thats a major terrorist attack and claim they were doing it for isis and all the terrorists are happy about that. But thats the problem, is that when they put a message out like that to everybody out there, you dont know it only takes one to get it in his head okay im going to do that and do it today. We saw a couple weeks ago in boston where the fbi had a wiretap and we are able to intercept the warning where he calls his partner and says im going to do it today. They already knew he received a hunting knife and had to intercept him at that moment. If they didnt have a wiretap on him and didnt have the surveillance on him, they wouldnt have stopped him. And possibly a Boston Police officer would have been killed that day. We heard from congressman peter king hes on the House Homeland Security committee. Listen to what he had to say. Theres great concern. Going back to dealing with the fbi, Homeland Security over the last two or three weeks, i would say this is the most intense level of concern i have seen maybe since 9 11. Tom, is it at that concern, post 9 11 . Yes. The concern is that an event is going to happen. I think theres very little concern, frankly, that they could pull off another 9 11 for the reasons i said. And even bin laden himself couldnt top 9 11 because, you know once the International Intelligence and Law Enforcement community as well as our own clamp down and tracked financing and messaging back and forth, and once he had gone into seclusion in pakistan he was not going to be able to oversee command and control over an attack like 9 11 by courier. We know one of the challenges for Law Enforcement, even in the boston case you say, it takes dozens and dozens of people on the ground to look after the surveillance of somebody that is suspected of being radicalized, a potential lone wolf. We have seen all the arrests that have happened just in the last month alone. Even this week there have been arrests here in new jersey nearby. How does Law Enforcement get their hands around this prob
