And yet we kill each other in these in these Mass Shootings at rates that are exponentially higher than any place else. Whats the difference . The difference is these guys with stack up ammunition in their houses, and thats sort of par for the course.

Tonight an investigation is under way in afghanistan after five americans were killed by friendly fire. A tyke from one of our own b1 bombers above. Jim miklaszewski is at the pentagon with what theyre telling us there. Jim, good evening. Reporter good evening, brian. For military forces this is the deadliest incident of friendly fire in nearly 13 years of the afghanistan war. Its one of the most heartwrenching moments for any mig tear family, a casual officer arriving today to officially tell them their loved one has died in the war. The family welcomed reporters after they learned that their son, their brother, 19 years old Army Private First class aaron tappin of illinois was one of those killed by friendly fire in afghanistan. U. S. Defense officials report the five americans, three special forces green berets, and two other u. S. Soldiers, were killed while on a joint mission with Afghan Forces in southern afghanistan. They were checking village security in advance of this weekends president ial runoff elections when, without warning, they were ambushed by taliban forces. An attash so fierce, the americans desperately radioed for combat air cover. An american b1 bomber quickly responded and unleashed at least one precisionguided bomb, but instead of the enemy, it struck the friendly forces, killing the five americans and one afghan soldier. We do have reason to suspect that friendly fire was the cause here, specifically friendly fire from the air. But the issue is under investigation. Reporter there have been 23 friendly fire incidents during the entire afghanistan war, resulting in the deaths of 40 u. S. Coalition and Afghan Forces. Besides the five killed this week, pat tillman, the nfl star who enlisted and joined the ranks of the elite arm rangers, was the only other american killed by friendly fire in afghanistan. The taliban ambush came as americas longest war is winding down, and most american troops are preparing to withdraw by the end of this year. Theres growing concern that taliban may try to step in and reclaim their power. Officials here at the pentagon tell us its just way too early to tell what went wrong in this fatal bombing . Was it human or mechanical error . The military has already launched an investigation to try to figure it out, brian. Our pentagon correspondent Jim Miklaszewski tonight, jim, thanks. Theres grim news tonight about the other of our nations dual wars, the war in iraq. After all the american lives lost, all those who came home grievously, mosul has fallen to the control of an al qaeda offshoot that is also advancing in syria. Our chief correspondent richard engel. Who spent years, of course, covering the war in iraq, is overseas with more on this. Good evening. Reporter good evening, brian. This is profoundly significant. This is not a tiny city. This is mosul, home to millions, controlled by an al qaeda offshoot thats actually even more radical than al qaeda. There was some heavy fighting, but mostly the Iraqi Security forces on which the United States spent billions of dollars and years training, mostly those iraqi forces judd walked away from their posts. They dropped their uniforms. They were scattered on the roads. The militants seized weapons, equipment, a lot of money. They seized buildings. Tens of thousands of citizens fled the city. This is all directly linked to syria. For years, syria has been pretty much ignored black hole. Militants in syria cross the border, they linked up with militants in iraq. Now theres one open front between the two countries. All week, brian, weve been talking about the potential threat of those five taliban militants released in exchange for bergdahl. Many u. S. Military officials ive spoken to say these militants in syria and iraq, tens of thousands of them are far more dangerous to the region and to us. Richard engel on the latest reporting for us tonight, thank. Back in this country, Hillary Clinton continue toss make headlines, including what she said in an interview with our own cynthia mcfadden, who spoke with the former secretary of state at her new york office yesterday, a first time shes allowed cameras on a tour. Cynthia is here in the studio joining us once again. Good evening. Good evening, brinen critics say her tenure was devoid of accomplishments. She gives herself an a in the job. Her hardest choice was going against the advice of other cabinet members and going ahead with the i know you say you havent made up your mind, but im going to give you the evidence from your book why i think you are actually running for president. Okay. Its in the context of your mothers death. Oh, right. Writing about her, she would say never rest on your laurels, never quit, never stop working to make the world a better place. Thats our unfinished business. It is our unfinished business, but i think theres more than one way to finish the business. Reporter one way, she says, is to continue her work at the foundation her husband started. Is this your hall . Is this your initiative . These are the people working directly with me. Reporter barbara bush recently said there should be people besides bushes and clintons who run for president. Dont you just love her . Shes outspoken and lays it on the line. Thankfully this is a free country and despite ute obstacles for running for president , anyone condition. Reporter whats the hard side . Whats against running for president . I was on this high wire of american politics and then american diplomacy for more than 20 years. I am about to become a grandmother in the fall, which i know will change mire life. I dont know how im going to field about that. I want to feel the feelings around becoming a grandmother. I dont want to be focused on something two years away. I want to be focused on this baby in front of me. I love my life right now. Reporter is being in the midst of all the politics of it, is that a factor . It is a factor. I think anybody who says it isnt either has never done it or may be trying to downplay it. It is. Our politics right now are very contentious, very dysfunctional. Reporter her 365page book generally sidesteps controversy, while galloping through the nearly million miles she traveled representing the u. S. The low point, of course, the death of ambassador Christopher Stevens and three others in benghazi, a reminder prominent in her office. Thats chris stevens. That picture was given to me by a young Foreign Service officer who was one of his best friends. She said i want you to remember what a kind and good man he was, and how he did what he believed in. Reporter if you had one doover from your four years it would be again ghazi. If i could turn the clock back and we could have figured out a way to avoid it, we certainly would have. Reporter looking back, there anything you personally feel you could have done differently . Well, in retrospect, if i have upended the way security decisions are made by security professionals, maybe, maybe not. Because im not a security professional. I mean, we set up a system where the people who are both on the ground and with experience back in washington make these decisions the i think thats right, although in this case, the findings where they should have done more. Reporter you have had said repeatedly you take responsibility for what happened in benghazi. I do. Reporter doesnt that include testifying in front of congress . Well see. Im not going to prejudge it. Reporter you write in great detail in the book what was happening in benghazi as it evolved. Did you keep a diary . I kept a lot of notes. Reporter if the committee wants user notes, would you turn it over . They can read it in the book. Lets see if its on the level or not. I dont want to be part of anything that in any way politicizes or demeans the sacrifice that we saw happen there. Of course there are plenty of people who believe it is Hillary Clinton who is politicizing the tragedy in benghazi. Brian . Interesting conversation, interesting book rollout. Cynthia mcfadden, a pleasure as always. Still ahead for us, the epidemic, the health alert out from the cdc, the exploding number of People Living with diabetes, and the problem is the millions who dont know it.

Then we gave each person a ribbon to show how many years that amount might last. I was trying to, like, pull it a little further. [ woman ] got me to 70 years old.
