Europe had more 20th century gun violence than the USA.
Mass killings in the early to mid 1910's.
Even more mass killings in the late 1930's and early 1940's right after Adolph banned guns in Germany. I'll be if you were a J living in Germany you'd want a gun!
Guns aren't legal to protect you from street thugs. This is the 2nd amendment... there right after the 1st amendment freedom of speech. It is so high of a priority to be there to give you a right to protect yourself from abusive governments.
I don,t see many people using guns against abusive governments anywhere. The governments ALWAYS have bigger toys. I see "some " people using them against kids and school teachers.
I love your second amendment, seriously, but it is not really working out very well right now , maybe exept for gun stock owners.. One hand gun for someone who goes thru extensive check to defend his family ,yes! One rifle for a hunter, yes
