my story is similiar... told it a while ago..
driving down south st towards leeming these punk kids (prob about 16ish) were throwing rocks at passing cars, and hit my car on tabs window (old car)
(this is at the lights at bullcreek) so they could hide in the bushes... unfortunately for them tab lives in that area and i knew my way around it so i turned onto the next street and circled around to catch them...
they were still there thankfully (now i was about 18/19 so a couple years older) we caught up to them and tab ripped a bike out of one of the dudes hands whilst i grabbed him, his friends (about 3-4 of them ran away from 2 people...i mean c'mon...)
i kinda roughed up the kid and was in a bit of a rage and then eventually let him go..
end of the story... yes i beat up on a kid that threw rocks at my car, he kept saying 'it wasnt me it wasnt me' i just kept saying 'i dont care, if it wasnt you get your coward friends back here so i can get the person who did, otherwise your taking the fall for them, great friends you have'
so im not really afraid to chase kids, i prob won't report it if theyre kids but if theyre adults i will... gotta go vigilante for this shit as the police can't really help as theyre juniors
