The PoPo locked up another 19 Occupiers last night, this time in the park behind the Schnitzer Concert Hall. The average age of those taken in was 31, up nearly three years from the bigger throwdown in the squares last month.

So far we haven't read any reports of serious violence, although the demonstrators messed up holiday shopper traffic downtown for a while by marching and standing in the streets. One guy climbed on the City Hall roof and briefly pitched a tent there.

From media accounts, it sounds as though it mostly devolved into a free outdoor dance party by people too young or too broke to get into a bar on a Saturday night. The 2011 version of cruisin', as it were. But the attempt to establish another tent city was reportedly terminated with extreme prejudice.

The police did their usual thing. They come in, make a big show with their batons, push some people, arrest some people, chase the rest, then leave -- so that the mob can re-assemble in the same place a few minutes later. This is what they did in the Pearl, in the squares, and apparently again now behind the Schnitz. Odd strategy.

Meanwhile, in a press release, the police tattled on some bad behavior by some of the Occupiers:

Officers noted during the clearing of the park that there were some children, ages ranging from approximately 8 to 12, near the front line of the demonstration. Officers advised to the parents to get the children out of the park but in one case, a small child was pushed to the front by an adult in apparent attempt to use the child as a human shield. There are no reports that any children were injured or had police contact and they ultimately left the park with adults....

Officers walking the area after the park closure located a cluster of spent shell casings on the east sidewalk of Southwest Park Avenue, along the back side of the Arlene Schnitzer Concert Hall. The shell casings appeared to be .22 caliber and 9mm (photos attached). There were no reports of gunfire and it is unclear why they were on the sidewalk in an area that demonstrators had been standing. In an earlier demonstration (different date), officers reported that someone in the crowd threw empty .223 shell casings at the police officers. It is not clear why or who is bringing empty shell casings to a demonstration.

Gee, do you think the cops being all dressed up in their Ninja Turtle costumes every time inspires any of that? Anyway, while we geezers cozied up at home, the young 'uns were keepin' Portland plenty weird.
