Yes and no
the usa might not be the most violent but usa is the example of the world for allot of country. I also believe that they should change there law. Because sending people to years of prison so they can come out and kill more people isn't going to work. where we live we a system that give people they help they need. and voila here every things goes allot better. just putting people away because it will ease your pain does not mean it is the best solution, if those people come out of jail with more hatred then they have been put into because they never got any help i do say they should change the system.
There allot of weird people out there who can easily get a gun and kill people, is that how we want to live, seeing every week another news bulletin of people being shot by weirdo.
