The problem Democrats have when trying to address crime is that their own governance makes it impossible to execute their plans.

San Francisco Mayor London Breed has been one of the leading Democratic city officials in focusing on crime. Her problem is that her city is in California, which is run by a Democratic supermajority that passes laws without GOP votes. That hampers the ability of law enforcement officers to do their jobs or makes it so that criminals can get off easy with weak penalties for things such as shoplifting.
