My pops grew up in communist Poland. When he was a teenager up until his early twenties he would go out and raise hell, party...typical dumb young punk shit.
Whenever the cops would come and break up the parties, gatherings...etc. About a dozen or so officers would run in and start indiscriminately beating the fuck out of everyone with their knight-sticks. No questions asked, everyone got their asses handed to them. There was no arrests, no bullshit. Everyone would just disperse and remember no to do stupid shit.
I think this picture is an appropriate place where it's a good idea to get a bunch of knight-stick wielding people to run in and just bust some faces.
