Actually, no, the problem isn't so much with the police as with the district attorney's office. The police can arrest these people, but it's entirely pointless when the DA won't prosecute them and they're back on the street in 24h with no penalty for their crimes whatsoever. I can't blame the police for not even bothering to arrest people they know will be let go immediately.
