The problem with that idea is that ANY law ONLY works for people willing to abide by the law. Criminal by nature are breaking the law, so WHO does the law effect? There are already 40,000 gun control laws on the books, not counting things like "it is illegal to kill people" and yet that does not stop it. What is one more or two more or even a thousand laws going to do to change that?
In most cases where guns are used to hurt/kill another they are either used in defense, so legal OR they are breaking not just one but MANY laws...........
Why is it in places like DC, CA, NY, ect that have very restricted gun rights there is WAY more "gun" crime then places where guns are more prevalent? How come in those places more criminals have firearms then law abiding people? Laws in those places restrict law abiding people from owning guns, but does NOTHING to stop the criminals.
