I don't own a gun, but I believe any substantive change is not going to happen because each side is not going to risk the wrath of the NRA and the millions of gun owners. There is alot of outrage, but politicians in the end are going to do what is right for their re-ellection odds--bottom line.All I can see happening is some watered down, more intenstive background check for weapon purchases, which would have had zero impact on yesterday's shooting.I think a good start would be tightening down on gun show purchases. I would be for a ban on assault type weapons--there is no reason for anyone to own an AK-47. If the excuse is you are a collector, then you can have one, but the firing pin or whatever (I don't know guns) is removed and it is disabled. It can hang on your wall.But even doing these two things wouldn't have changed a thing about what went down yesterday. I don't know if a stop gap is some Federal funding to make sure each school has the ability to hire on armed security officer wouldn't make some sense. I know most schools here where I live have an SRO (School Resource Officer--which is a regular city cop) on staff and usually on site every school day. There is no easy answer here because how are you going to stop a crazy person bent on doing completely unspeakable acts?
