Public defenders have an adversarial relationship with police. They don't have to worry about pushback because the police were never going to help them anyways. Public defenders also don't really have oversight of police. They might be able to get the evidence from a particular act thrown out of court, but they have no authority to levy any kind of punishment. They can't file charges against anyone, only the DA can. I think this makes sense. Part of the issue is that the DA and the police work on the same team; there's a clear conflict of interest. They should also grant the power to file charges to a party without conflicts of interest, if there were any to begin with.
