Crime isn't being prosecuted, the criminals know it, and this breeds more crime (and more criminals). Even when they are imprisoned and incarcerated, they're probably in jail for somewhere between 24 hours and a few weeks. They know pretty much everyone else in jail, so it's almost like going to a camp reunion for them.
There used to be BOLO "be on the look out" lists with grids of mugshots passed around various informal circles so that businesses and organizations can better protect themselves from crime. But, mugshots are no longer public, so they can't even do that anymore. It ends up creating more profiling of a person based on their appearance.
And... more surveillance.
