Dude... I honestly think that by either eliminating the sale of assault weapons or creating/implementing a system of gun registration will decrease the incidence of gun related homicide... basically it comes down to - the more guns you take out of the equation, the less deaths(from guns) you will have. Its as simple as that. If you try and argue that point, you are either fucking ignorant, or mentally handicapped.
Yes I realize that there are fucked up people in society, but if its exponentially easier to buy a gun than it is to get a psychologist/ help for people who have serious mental issues, then we have a serious problem.
