Yeah, I knew a Brazilian that claimed Brazil didn't see the need to legalize gun ownership because they are a peaceful people. My response was something along the lines of "people are people". Of course, her history professor said we used the atomic bomb on Japan as revenge for Pearl Harbor. *shrugs*
That's okay, I know gun control is baloney. You've already brought up Switzerland. Inversely, Colombia has very strict gun control laws, but proportionately beats out the United States in gun violence. Again, humans are what they are. Cultures and laws may make one thing more likely than another, but someone will always prove that anyone can do anything.
