Dealing with drunks and drug users sitting on the wall after work.

I came home from work and 8 drunks and drug users or so were sitting on the wall in front. I asked them to leave one girl tried to act like she was calling 911 on me but I knew the protocol since I have to call 911 so much and I wasn't buying into her bullshit. I called 911 since they refused to leave and someone tried punching me while I was talking to 911, I had to pull out my protection and then some of them left and the rest ran as soon as they saw the cops coming. The video from the front camera ended up being a corrupt file for some reason, but this video pretty much showed what was going on with 2 of them. I only used protection to deescalate and would not use it unless it was my only choice.
