I am not a fan of guns by any means, but banning guns is going to cause more trouble than leaving them...

There is no way you can find every single gun in this country and take it away from them. Basically, the police would have to go door to door and rip everyone's house apart looking for guns..

Also, if you took guns away from people, you know the Black Market will make a fortune smuggling in guns from the underground. Anyway, even if by some slight chance that they take every gun out of this country you should think about this: If a frustrated man who had his gun taken away from him gets a new gun from the black market goes on a shooting rampage, well you know what happens next....

Banning guns in the United States would be a win for the Black Market
