Turnabout's fair play, sweetie.
Seriously, this is what happens when the public, even the decent law-abiding people, start to believe that the police are either no longer on their side, or (worse) not worth bothering with because the hassle of 'getting involved' is not worth the trouble, and if there are consequences as a result of you coming forward from the scum in question, they will be useless at dealing with them.
Cases like the one referred to in the link below don't help, either.
Check the comments. They say the same thing.
