OMG!!! Assault snowballs!!!!!
I grew up in NYC, and several of us, friends and family, girls and boys, were having a rock fight in my local park with some other kids from the next block...and a young red-headed cop came by and slapped his baton into his hand a few times and told us he was going to “club youse guys” unless we stopped right then and there. We did.
Later he came by when we were sitting around on the stoop and told us that this was stupid behavior and we shouldn’t be doing it...which of course, we all knew. And he told the same thing to the “other side.”
Pulling a gun was probably the only way to get attention. The billy club got my attention, but that was 50 years ago...
