Talked with a buddy of mine today who is a retired LA Sheriff's deputy and he said that "king" Rex is talking out of his ass pretty much.
If the LASD incarcerates someone for a violation against a municipal ordinance only, basically a misdemeanor, then the city has to pay the LASD to confine said individual. He did clarify that if someone is arrested for a felony in conjunction with other violations of municipal ordinances, then the County pays as the felony is the presiding cause of incarceration.
So, as long as people just gather and protest the "king" and don't engage in any felonious behavior, then it's highly doubtful anyone is going to see the inside of a jail cell.
But it's good to see the "king" with no clothes so to speak.
