I've been harassed and threatened several times on the streets of downtown jersey city, every time by teens. I frankly just stay away from teens now.

I have indeed thought many times about what I could've / should've done, it's somewhat comforting to see many people agree here there's not that much to do.

None of the situations ended in violence so perhaps de-escalation and trying to get away is ultimately the best answer... sorry this happened to you too.
