One protester called a police officer a "pig?" That is so 1960s.
Protests in the 1960s were highly organized and financed by communist groups. That "pig" slur alone proves to me today's protests are organized and financed by the same bunch.
@mountaineer I guess the police have been told to leave these protesters alone. If the protest is by a certain ethnicity, religion or highly organized communist group of agitators, police are told to stand down. Now if it had been, say, a conservative group of white, anti-abortion Christian protesters, they would be loading up the paddy wagons. There are certain protected groups or classes that can do whatever they want. Don't belong to any of those groups or classes? Then you are in trouble.
