Schizophrenia and bi-polar doesn't show up in people until their early 20's. Ridlin might also be a problem. This needs to be studied. I believe ANYONE who has ADD, or is diagnoised with any type of mental disorder, should be put on the no gun list. The doctors should be required to report anyone on medications or has these type of mental disorders should not be allowd to buy a gun. Now, stealing a gun etc involves another crime. Like the guy in Oregon, his was stolen. Don't know about this guy. Just like the guy in Colorado and at VA Tech, they should have been reported by their doctors and not allowed to buy guns. I think the law already states this, but doctors never report these people to the FBI to get on the no buy list on the computers. I think the doctors should be held accountable if they do not report this if they believe the person might be a danger to themselves or others. Also, how did the guy get in the door with guns unless he had a heavy or big coat on. Arming the teachers would have solved part of the problem. Only a few would have been killed before he was taken out.
