That is often addressed through lawsuits

[Major Nikon]

Prosecuting the offenders doesn't address the situation if nobody is willing to change. They can always hire more cops. When your taxes go up or the police force has to do without, people often start to question if the status quo is worth it. Then again Sheriff Joe is still in business despite tens of millions paid in lawsuits with much more in the works. Some people really are that stupid.
