The first video show a park ranger whom I have conversations with in the past, is warning a man resting on his sleeping bag that he is in violation of a city code.
"Ranger Watching 10 24 13 South Park Blocks" (No laying on a Sleeping Bag in the Park) - 8:45 minute video
The second video happens as I see a police car turn up the street the wrong way and park on the trolley track to stop and arrest a man.

Also it is good to know, there is here in the Portland "area" the FTP folks (Film The Police) who have a facebook page and meet up about once a week to film the police in Portland (usually but not always) on Saturday evenings!
