I personally believe the laws are the least likely factor as to why the US has so many shootings. I think mental illness is much more prominent in the states, and goes untreated much more often. Also, there is some real trash in America. I know it exists everywhere, but even middle class families, so many of them are just terrible, terrible parents. Parenting is something that needs to be looked at as an issue, because nobody talks about it until its too late and they say "where were the parents". Granted, you can be the best parent in the world and still end up with a pile of shit, but I think a lot of people who have committed these acts probably didn't have the best support from family.
I can believe that. It's all the more reason to restrict access to guns though
