SFPD False Arrests? - M15 Breakaway March

SFPD forced breakaway march onto the sidewalks. Some decided to do civil disobedience, others kept marching (mostly on the sidewalks). A woman was arrested on Market street, apparently for jaywalking. Tourists, bystanders, peaceful dissenters, and possibly a few would be window breakers were later boxed in, surrounded, and arbitrarily arrested - for walking on the sidewalk? I witnessed zero protester violence or property destruction.
