Probaly 300 citezens of mexico who have invaded the USA and broke more laws throwing things at and scaring the driver of the van half to death. He could have been pulled from the van and beatent to death by the mob, instead he was arrested but the lawbreakers go free.
America is lost.
Absolutely right. Most of them probably are illegals. They have no fear of U.S. "law enforcement" anymore.
But it's better than that for them -- the cops are now on their side. Leading to the question: which people, and which country, do the police get their legitimacy from? Who do they "serve"?
The police are nothing more than private citizens (we hope they are actually citizens) hired to do a job that the citizens themselves believe needs to be done by a trained group: enforcing their laws. The police are not a sovereign entity unto themselves, nor are they elected. They derive their legitimacy as a force from the citizenry.
If they now side with the citizens of another country against the citizenry which legitimizes them, they are no longer a legitimate force. In the case of the Garden Grove cops, and a fair number of police forces in California, this is what has happened.
