I had to seethe a bit before I could think while watching that.

It's getting cold in Portland and the homeless find ways to go to prison where it's warm. The prison guards call these folks the Regulars. The story I always heard was the guy who was at a light and stop a stopped cop car, so he took a wizz on it.

This means all the regulars are willing to do anything to get out of the cold. It's messed up, and has been getting worse every year.
