For what it's worth. . .
FORGET about it!
I used to work as a police officer in Salem, NH. Invariably we would bust some punk ass kid and escort his skinny rear end back to his folks.
For the "first-timers" the parents acted as you would expect: They'd cry, yell, get pissed, what-have-you.
A TOTALLY different dynamic for the "repeat offender", though: THEY BLAME YOU!!
"Leave the poor kid alone"! "Why don't you PIGS find somebody else's kids to pick on!"
Even in car chases, we have had parents say,
"He wouldn't have ran if you didn't chase him!" And this is from parents of 14 year olds who had stolen the damn car!!
Best way to stay out of (legal) trouble is to avoid it altogether. These kids and their pathetic parents BELIEVE that they're victims of "the system". Don't give them another reason to spend another day in court. . .This time SCREWING YOU!
Let the punks mouth and play their petty ass games. Laugh the way you would laugh if a 4 year old said or did the same thing.
Remember: Most "threats" are threats to our ego, not our personal safety. Forget trying to save these punks by teaching them a lesson. Society has already been failing for 14 - 15 years. What they hell could you or me teach them in a day?
I feel your pain, man, I really do!
