The US is horrible for gun violence, theres no doubt about that. This is probably the result of a lack of gun control. People just buy guns for the sake of saying im excerising my right. That may be fine to some, but if you want to stop crime you need ot start developing a process where people must get safety training, screened, references should be consulted, and so on. Guns are weapons, they shouldn't be as easily accessible as groceries or toys. Countries with good records of preventing gun crimes typically have a comprehensive process one must go through before receiving a firearms license.
