Indeed, in my experience all these tools do is offset policing to "easy" crimes and the harder problems continually get ignored. It's largely been accepted in my city, for example, that traffic enforcement no longer happens.
If I would have to rate difficulty of Traffic enforcement, I would have put it quite low... What makes it so difficult?
A "fun" observation I've had is that politicians and police tells us that they are focusing on crimes that increases the perception of safety. Then for some reason they spend time on petty drug deals, gangs that mostly fight internally and other crimes that the average person would never experience.
If they wanted to do something to increase feeling of safety, and justice, they'd crack down on bike theft.
