Norton,
You are forgetting something. All the departments you mentioned have unions. The biggest ones are the police and fire departments.In fact, they all have unions. LA is a very union friendly place. That is why nothing gets done.
The people are going broke and can no longer support the crushing weight of bloated corrupt unionized government police/fire mobs.
It's not that complex. The people have no more money to support this level of corruption.
The LA Police Protective League has 9800 members.
