We are living in the safest era in the history of humankind.
Bullshit!
When I was a kid, I could safely hitchhike to a town 20 miles away in complete safety.
Nearly every boy carried a pocket knife, but wouldn't ever consider using it against someone who dissed him.
Every fall through high school, there was a shotgun in the trunk or cab of 1/4 or the vehicles in the student parking lot, not because we were going to shoot a teacher who pissed us of or we felt "depressed" but because we were going hunting after school.
Cops rarely had to fire their guns because we complied with their directions and wouldn't consider trying to rush them and take their weapon.
Safe??? Hell no! We haven't been safe since LBJ.
