This isn't a recent development... it's gone on for ages...
But thanks to my physique... the over 6 foot, fridge with arms kind... only the stupidest of the stupid ever tried anything.
Luckily, nothing like this goes on in my area, only have to deal with kids that are so rich that they think problems don't exist and have a handful of braincells between the lot of them.
My favorite memory of issued like this, from back home in good ol England, was when I just heard a "HAY YOU!!!" only to turn around and see this pint sized kid charge at me.
He leaped into me, bounced off, hit the floor quite hard, and just started bawling his eyes out.
Apparently, from what I heard the day after because the police came to ask me what happened, he had broken his collar bone from landing on the floor and 2 ribs from hitting me.
Since I had 2 witnesses to this event, they knew the kid was lying, and the cops pretty much said that the little shit deserved it.
