More on protestors at 14 year old boy's house

What the heck is going on that even the police are supporting these thugs? This was an appalling situation where 500 people driven in 14 buses descended on the private property of this individual, who wasn't even home, and screamed and chanted and made scenes, yet the police chief says, well, they didn't see them and they were all peaceful and not a problem. Ugh. The police chief appears in this interview to be a union sympathizer.
