Firstable USA population was x times smaller then today and less civilized, and less everything like video games, porn and drugs so pls do not compare...Im sure I can find at least dozen of school shooting cases from 60's but I do not intend to.
There's one more factor whoch should be rised here - minorty...I mean whos is who?
Balck people in 60's and white people 50 years later? I bealive hers's your goal.
For me the most vaulabe reason of rise against guns is a fact that rest of the world can live withouot it and by the same time not having any school shooting or terrorist attacks...
BTW guns in Swiss are ALLOWED...but guess what...nobody here heard of any civil shooting form centuries...
Have a good day getns.
