This is very old school, but I can recall folks saying of justice, "If the law won't take care of it, it's just-us."
The sad part is that when the courts and police will not do their jobs, not because they cannot build a case, but because they
will not build a case, an important distinction, there could well be a return to that style of dealing with 'social problems'. On the current trajectory of some agencies, it is more likely a probability than a possibility.
