Were they eating pasta and trying to direct traffic?
I am unsure if there is something I have seen that is more pathetic. If anyone with any skill was actually aggressive they would scatter like mice. There is probably a good mix of legit mentally ill, drug addicts, and people that actually want a better world.
As much as it would feel good to engage and "teach someone", the best is to just put on a good podcast and tell whomever you will be 20 minutes late. Keep the windows up and the doors locked. Weapons come out or they try to breach (all of which they are too weak to do) then it is game on. I might take the time to put in into 4 wheel low.
