Well stay on top of this story as bring more details as we get them. President obama has now done what no other sitting u. S. President has done before in american history. This morning mr. Obama visited the inside of a federal prison. His tour near Oklahoma City has included visits with inmates and talking with Law Enforcement officials. This hour he is expected to deliver a public speech from the prison. Its part of his effort to reform the nations criminal justice system. Mike how significant is it for the white house to have the president there at this federal prison . Reporter well, as you said hes making history being the first president to conduct such a visit. This is one of those moments in this time a Tipping Point where republicans and democrats are coming together over an issue where you really think they could dont that and that is federal sentencing reform federal prison reform. The Violent Crime rate in this country is at the lowest rate it has been since the 1970s, and yet the rate of incarceration still near or at record highs, and that includes federal and state prisons. The president in this federal facility is keeping up a theme that he has kept up all week long, on monday commuting the sentences of some 46 individuals, mostly nonviolent offenders, tuesday evening makes a speech to the naacp, and now on thursday, with many events in between, concerning the deal with iran, the president making this undprentsed trip to a federal prison facility. How important was it that they choose this prison . Reporter well, you put your finger right on it. The president is trying to focus on nonviolent offenders. A lot of people put the source of the overpopulation in prison problem in this country to the socalled war on drugsover the 80s. The mandatory minimums and what is curious about that is you now have republicans jumping on board trying to institute reforms themselves. Yes, they are concerned with what also of this is costing, its costing billions of dollars, some 7 billion just on the federal level each year but john boehner the speaker of the house said this morning, some of these folks are put away on flimsy pretenses. I think we should remind our audience were going to be brings the president s speech outside of the prison when he delivers it. The security situation for the president is actually easier at this particular event, as opposed to a public event. Right david and we have been to countless president ial represents where everyone in the public is swept. I guess you literally have a captive population there, where presumably everybody is considered to be without weapons or without anything to potential i will harm the president. Mike thank you. The United States has the highest incarceration rate in the world, but as the u. S. Prison population grows, so does evidence of its harmful social impact and not just in terms of money it costs. One u. S. State is already aggressively exploring alternative models of justice. Reporter as the second whitest state in the u. S. Maine is not renowned for its ethnic diversity, but here amongst the buildings, a program is underway routed in Global Indigenous cultures. It asks fundamental questions about the nature and purpose of criminal justice in the u. S. Prisoners are being released early so they can learn from their crimes. It hurts the family. It hurts, you know, the surroundings, such as the community. Reporter the key is talking within a circle. Are kind of five keystone questions that we think about. What happens . What were folks thinking or feeling at the time . What have they been thinking or feeling related to it since it has taken place . Who has been affected and in what ways have they been affected . And what needs to be done to make things as right as possible. Reporter juvenile offenders can escape incarceration all together. There are too many people in prison. Reporter charlotte is a gallery owner who chose to confront the two boys who robbed here to make them understand why what they did was wrong, instead of having their lives potential lived by jail time. Just had the feeling that the kids who had done that had never really felt connected with with the community. Reporter Restorative Justice began to catch on as incarceration levels reached records. In some states modern u. S. Law enforcement is looking to aboriginal tradition. It was in their best interest to bring them to the center and say you have really messed up and we have got to figure out a way for you to learn from your misbehavior to make it up to the people you have harmed and to return to being a functional productive member of our community. Reporter this boy would still be locked up had it not been for the Restorative Justice program. He broke into and vandalized a house when he was 12 years old. He since worked for the home owners and paid them restitution. The first meeting was really emotional, because he was telling us how much damage we caused. Reporter he is returning to school soon. He is clear about his goal. Its on your arm. Yeah i just got that the other day, actually. Rrpg and those like him are less likely to reoffend and almost all of those offended against feel justice has been served. And now to theclear deal with iran. Vice President Joe Biden is back on capitol hill again today, trying to convince u. S. Lawmakers to go along with the agreement. Hell talk with democrats on the Foreign Relations committee today. Nancy pelosi said this morning that she will support the deal. Grait britains foreign secretary says the deal with iran ensures that the country will remain peaceful. We believe removing the threat of a uranium bomb which we are confident this agreement does, while allowing iran to reengage with the International Community is the best and perhaps the only way to build overtime the trust that will allow a dialogue on the many other issues we have with iran. The British Foreign secretary jest met with one of the harshest and most vocal critics, israeli Prime Minister benjamin netenyahu. Mr. Mr. Iranians say they have high hopes for their country once sanctions are lifted. Ali velshi met with Business Owners and entrepreneurs with dollar signs in their eyes. And for them choosing money over Nuclear Ambitions was a nobrainer. Translator we need to have relations with the world. We need to export what we make, and import some things that are not worth creating in house. Reporter this is an executive in a car parts factory west of tehran. He is hesitant to talk politics but eager to tell us that given a choice between Irans Nuclear am bigses and the countrys Economic Prosperity, he would choose integrating iran back into the world economy. Translator in this you yeek moment in time, iran needs to move away from its oil exporting base. Reporter this is part of irans auto industry, one of the largest in asia. It is second onlying to irons oil and gas industry. He said the sanctions forced him to make parts instead of importing them. Now that sanctions are about to be lifted he thinks iran is ready to export cars to the world. In addition to oil and cars sanction taken a bite out of the persian car tet industry. This is a trader working from his small shop. A few years ago business was so good, he was sending a shipping container full of carpets to the United States every week. But the sanctions stopped that. Translator some 20 of our population is involved in this industry. We have coloring workshops, sellers, dealers, when we cant export our product abroad we have to depend on local demand. If sanctions get lifted well see a boom in our industry. Reporter the sanctions imposed are amongst some of the tougherest ever imposed on a country and the effect has been rampant inflation. In my hands i have 3 million real of the currency unit divided into 5,000 notes. This is worth 100. And three years ago this was worth 250. One way iranians try to hedge the inflation is to buy gold thats why this man says his jewelry business tends to do well in good times and bad, still he says irans plummeting currency poses challenges. Translator program of 18 carat gold we have in one day. And in one hour we have so many different prices. It causes us many problems. Reporter despite the hardships sanctions pose for most local hightech entrepreneurs tell us they offered opportunities that otherwise wouldnt have been there for them. This man is founder of saba idea, a Technology Firm that has taken off with a youtubelike product. Translator sanctions increased our cost of research and development, because we werent allowed to collaborate with Foreign Companies abroad but we also benefited from the sanctions, because they forced us to develop products and services on our own. Still i think once sanctions are lifted, we will be able to deliver our product with more efficiency. Reporter and now that a deal on Irans Nuclear program is in place, many in iran are hopeful that the chances for opportunity and Economic Prosperity will only grow. Ali velshi al jazeera. We want to bring you up to date on some of the breaking news coming out of tennessee. There has been a shooting in chattanooga. Here is what we know now. The u. S. Navy says there was a shooting at a Navy Recruitment center, which is near a highway. There had been initial reports it was a u. S. Naval reserve center. But that is not accurate. You can see the police tape there. Local malls and a nearby Community College have been locked down. A hospital nearby is also onaid to have received victims. The major confirmed that it was a Police Officer who was shot. We have got an officer down. We had somebody out there shooting at our army reserve center. This is one this is a very very terrible situation, and we need to go figure out how we can handling it. Police are not sure if the gun plan has been exactly where the gunman is. But in any case the manager of the broadly square mall where this happened confirmed that the mall is on lockdown. And this particular mall does house a Tennessee National guard recruiting center. And it was put on lockdown. The u. S. Navy says that an earlier tweet that this happened at a Naval Reserve center was incorrect. It did happen at a Navy Recruitment center and you saw the report that the bradley mall has been put on lockdown and there are several reports about the Police Effort to try to find the gunman responsible. But a lot of facilities have been put on lockdown as a precaution. Police have closed several roadways and highways. As we get more information well bring it to you. Now to greece that country is getting a cash infusion less than 24 hours after lawmakers agreed to reforms and deep cuts. European creditors have agreed to a 7 billion bring loan. The head of europes Central Bank Says its the First Step Towards getting the greek banks back open. The European Union ministers will start a discussion on a bailout for the nation. Simon mcgregorwood has more on the developments. Reporter with this announcement its sweetening the bitter pill for mr. Tsipras who pushed through this deeply contentious package of laws last night at great political cost to himself. It is a little bit of relief a little bit of reward from the european creditors, if you would like, to allow a little bit more money into the system. We are even hearing rumors that some banks may reopen as soon as monday. So its a little bit of breathing space. Were by no means out of the woods yet. One of the things he did say that was encouraging for the greeks as well i think, was he spoke very confidently about the greek government paying back a 3. 3 billion Interest Payment on a European Central bank loan which falls due on monday. In that would suggest, the experts say, that this bridging finance of about 7 billion euros that the greeks desperately need in the next few days is pretty much going to be confirmed probably tomorrow. So, again, the connection that mr. Tsipras can make to a very skeptical greek public we take these difficult situations and they are connected to our situation being made slightly easier. Mexican drug lord Joaquinel Chapo Guzman is still on the run, and now were getting an up close look at how he escaped. Reporter behind me is the maximum security prison where many of mexicos more dangerous or high profile criminals are locked up, and none of them are morneau torturous than Joaquin Guzman who was captured and taken here in february of 2014. Cell number 20 was home to the worlds most wanted drug lord for 16 months until last saturday evening, in which he sat down on the bed of his cell and put on his shoes. He then got up and went into this area which is one of the only areas in this cell where the cameras cant see him, and he then knelt down and kept going lower and lower until he actually disappeared into this hole which then goes down into a tunnel which extends for 1. 5 kilometers. It is worth noting that this prison is a huge maze and we passed through so many corridors and so many security doors just to get to this cell that its impossible to know where exactly you are inside. And that makes it even more amazing and suspicious that el chapos residue team new exactly where their tunnel had to come up. And behind me is the building where Joaquin Guzman eventually emerged after going 1. 5 kilometers in his underground tunnel. A luxury tunnel that has ventilation, electric lighting and even a motor bike. There is now a manhunt throughout the country to try to catch him. Mexican authorities are offering a nearly 4 million reward for his arrest. George h. W. Bush is in the hospital after breaking a bone in his neck. His Office Released a statement saying the elder bush never lost consciousness. He is the oldest living former living president in the United States.
