First the Canadian thing; my brother in law gets married, takes his new wife to Canada for their honey moon. When they get to the border they strip search his truck and he ask why are you doing this, your not doing this to anyone else? The answer; your license plate say Texas, everyone in Texas carries a gun. This was 25 years ago
As far as the shooting of the 11 year old for ringing the doorbell, that should never happen. Kids have been knocking ringing door bells forever, thank God I was never shot. People are just angry today, very short temper, look at road rage, I never use my horn, not taking a chance.
