Reporter bush said the focus should be on the victims families and he has compassion for those calling for stricter gun laws, but disagrees. Name a case where gun rights being restricted out of washington would have changed the course of any of the cases. The bigger problem right now is that we have team that are, having growing despair, that are isolated from society, thats are disconnected from the rest of us, and spiral out of control and then commit these atrocious acts of violence and in many cases commit suicide. Despite a fundraising and organizational advantage bush runs fourth or fifth in polls in early voting states and nationally. There is now talk of bringing former president george w.

A new study out today found that patients are often charged drastically different prices for the same medical procedures. Dr. John lapook looked into this. Reporter in 2008 when Nancy Marie Bergman of merrick, new york, was diagnosed with Breast Cancer she struggled not only with her disease but with figuring out how much it would all cost. It put more stress on me than the actual diagnosis of cancer. Reporter todays report by Cast Light Health which studies Health Care Costs ranks cities the price by common women services, office visits. Hpv screening and mammography. Sacramento, california ranked highest on mammograms at average of 485 compared to 159 in cincinnati. Michelle scott is general counsel for fair health, a Consumer Organization that tries to make Health Care Costs more transparent. Has there been anything that just knocked your socks off . I think sometimes the fact that there are such disparities in pricing and that they can occur within blocks of each other. Reporter for example, a mammogram done for suspected cancer where bergman lives costs 211. 30 miles away in teaneck, new jersey, the same test is 95. Why is there such a wide range of prices for the same procedure . There is a wide range there are a lot of different circumstances and the costs may be driven by other factors, overhead, rental considerations, and the methods that different doctors use to perform the procedures. I think consumers need to take a more proactive role in their health care. There are tools they can use in order to make proper decisions so that they can be the educated consumer which we need to be in todays day and age. Online tools can help calculate medical costs based on your zip code. Michelle scott acknowledged it can take a lot of work to learn the details but she said we dont usually buy a house without checking out what the mortgage terms are.

Major tom we end tonight with a man who traveled into space and turned into a star. Heres jim axelrod. Reporter when canadian Astronaut Chris Hadfield blasted off for a five month stay on the International Space station in 2012, a few thousand people followed him on twitter. We had a million by the time we settled back on earth. Reporter how does that happen . All i was doing was saying i am a human being doing something unusual and new and you are welcome to come and look if you like. Reporter they did through the snapshots he tweeted and videos he posted, from everything making a sandwich in space to crying in zero gravity. If you keep crying you end up with water. Reporter hadfield provided new views of life from space with a remarkable accessibility.

The First Canadian to walk in space, he is on the back of the canadian 5 bill. But his new found fame its broadening his capacity to inspire. I was struck by one headline calling you the most famous astronaut on earth. Pretty big title. Yeah, it is. Social media allows access now where you can look through the eyes of an explorer and get insight into what it is look to be right on the edge of human existence.

And lightly land upon the bed and lay done to sleep reporter a 53yearold retired canadian astronaut and his guitar is leading a new generation of space lovers positively star struck. Lay down now to sleep jim axelrod, cbs news, toronto. Thats the cbs overnight news for this thursday. For some of you the news continues. For others, check back with us a little later for the morning news and cbs this morning. From the Broadcast Center in new york city, im scott pelley. Announcer this is the cbs overnight news. Welcome to the overnight news. Republican president ial candidate dr. Ben carson sparked controversy over what some are calling insensitive comments about last weeks massacre at a Community College in oregon. I would not just stand there and let them shoot me. I would say, hey, guys everybody attack him he may shoot me. He cant get us all. Take action. Absolutely. Hopefully will not have that happen. Reporter the comments havent hurt his showing in the polls. Second to donald trump for the gop nomination in three swing states. He sat done to discuss his views on Mass Shootings on cbs this morning, with charlie, nora and gayle. Good to have you here. Thank you. What did you mean when you said i would not just stand there . I want to plant in peoples minds what to do in a situation like this. Because unfortunately this is not probably going to be the last time this happens. Do you believe the victims in oregon just stood there . From the indications that i got they did not rush the shooter. The shooter can only shoot one person at a time. He cannot shoot a whole group of people. And so the idea is overwhelm him so that not everybody gets killed. Do you know who chris mintz is . No. So he is an army veteran. He was shot seven times. He did actually rush the shooter. He is being hailed as a hero. He blocked the door and saved peoples lives. Some one in the incident did act heroically. That verifies what im saying. Thats what should be done. If everybody does that the likelihood of him being able to kill as many people diminishes quite significantly. You are being accused this morning of being insensitive to the victims. People say look you dont really know what you will do if god forbid you are ever in that situation. How do you respond to that . I respond to that, we live in a culture now where people decide that everything you say we need to set up battle lines and we need to get on this side of it or that side of it rather than, collectively trying to figure out how we solve the problem. Its, its sort of an immature attitude it seems to be something rampant in america today. The question is what do we do about this . I mean everybody expects it will happen again. The president said it has become routine. So how does a nation come to grips with this fact it is a combination of who is doing it, access to weapons, and the opportunity . Well in medicine we have a tendency to make decisions based on evidence. Not on ideology. So, lets say this were a disease, what we would be saying is lets take each one of these shooters and lets go back and lets study their lives. And lets see if we can see some commonalties here. Are there some Early Warning signals for people like this . So that we can begin to identify them and intervene before the tragedy occurs. Not only for the people who were shot, but for the shooter themselves. How would you do that . Number one. And secondly, once you begin to see a pattern how to you make sure that pattern will help you lead to the next potential assailant . I think we have to for instance, empower the psychiatrist. The psychologist. And number these cases, these people have already been working with Mental Health professionals. Nothing was done about it. We have to be able to move to the next step. Not just recognizing that their mentally ill, but being able to take the, appropriate interventional steps. Should there be new laws to make it harder for people who have Mental Illness to purchase guns . For people who have been declared dangerous individuals by Mental Health professional absolutely we should be looking for a mechanism to keep dangerous weapons out of their hand. Now, you know we need to study all the possibilities. And we cannot do anything that compromises the Second Amendment. But as long as we keep in mind, we dont want to compromise the Second Amendment. But we also want to keep dangerous weapons out of the hand of dangerous people. That makes imminent sense. At the time of the Second Amendment they were talking muskets, werent talking ak47s and rifle tuesday, you write in your book you, thought the ban on military style assault weapons was a good idea. You have now written you since changed your mind. What changed your mind . Youll also see that, that i talked about the fact that they recognize that things would change. That we would become a more modern society, we face different principles, different situations but we had to recognize that it was the principles that were important. So what were the principles of the Second Amendment . Those principles were we wanted to make sure that the people had the ability to assist the military in case of an invasion and that the people also had the ability to protect themselves from an overly aggressive federal government. That was a very important part of the reason for it. Now, obviously, if we say well we are talking muskets. So yeah, you can have a musket. As we advance in terms of our weaponry. You cant have any of those things. That violates the principle. Michael bloomberg is also close to the university you work, johns hopkins. And a proud graduate. He has become a very, very strong advocate for gun control. What is it that he doesnt understand that you understand . I think we ought to get him to answer that question. Let me go with you first. And then. What i understand quite vividly is what Daniel Webster said. Daniel webster said america will never suffer under tyranny because the people are armed. Thats what i understand. So i dont want to see tyranny occur here. Cant adams also said that there may come a time when we do not have good people at the helm of our country. We cant always assume that it is going to be that case. You criticized president obama for going to oregon to meet with victims families, you said it
