You guys must be new in town, this was an everyday occurrence in the 2000s and 90s in JC. Packs of teens going out and assaulting people for shits and giggles. Both of you are lucky it didn't end up worse, I can recall at least one such occurrence within the last decade where an older man was knocked out by a group of teens and he fell on one of those steel fence decorative spikes and died, some real final destination type ****. The biggest problem in JC was always the packs of teens going out to commit chaos.
