Have you done the math on how much it would cost to attempt to remove every single firearm from every single legal and illegal person in this country? Not just in terms of financial cost, but in bloodshed also? You think some of these gun nuts are going to just walk up to a police tent set up in Wal-marts parking lot and hand over their guns on 'turn-in-your-gun-day'?
Don't get me wrong, i dont like the NRA's answer at all. But I don't think banning assault weapons will do one damn bit of good. Several mass killings have been done with simple handguns, so unless you want to ban every single firearm, banning assault rifles will do no good. Oh it might make people 'feel' good, like they really accomplished something, that is, until the next mass shooting happens, then everyone will be standing around scratching their heads like WTF just happened? We had LAWS against this.
The cat is already out of the proverbial bag on guns in the U.S. last I read, an estimate of 280 million firearms in this country. You will NEVER get rid of them. And, I know our Euro friends dont understand this, but this is a big, big fucking country. Much easier to try and control these things if you live on an island, or live in a country the size of Sweden. The only way you remove all guns in this country is to send the military and national guard door-to-door and have them confiscate and turn every single residence in this country upside down looking for them. That would never happen. We would be talking about the next civil war if anyone in power thinks that would be a good idea.
Another big question is, do you really trust your government on gun control? This government, who has no problem sending weapons wherever in the world and putting them in the hands of bad guys as long as those bad guys aren't as bad as their own leaders. Hell, this government just put 2,000 weapons into the hands of some of the most dangerous cartels in Mexico.
Realistically, these things will never stop, I dont care how many feel good laws you want to pass. Criminals and sick people are going to do criminal and sick things. How many billions of dollars and lives have been wasted on The War on Drugs, yet I can still go across the street and buy a dime bag, or go a little farther into the city if I want something a little harder. You think a war on guns is going to do any good?
I think the only realistic solution is to try and identify and keep tabs on the seriously mental ill people in this country. Do whatever we need to do legally to deny access to guns for those people, and possibly go so far as to deny legal gun ownership to parents of seriously mental ill children. Adam Lanza's mother should NEVER have had those weapons in her house knowing she had a child who was so disturbed that he probably needed to be committed to a mental institution. But then who is to say, if he was determined enough, he could have still gotten hold of as many guns as he wanted, through some other means, legal or illegal.
