I think that you have hit on a very important point here. This is serious business, in my view mostly because considering the present regime in Washington (and their counterparts in my home state of California) this Republic is in dire danger of descending into what could rightly be called a tyranny. So I want to keep my powder dry, so to speak, and reserve that language for the dark day that seems to be looming.
That said, our rights are being violated, materially, every day by government apparatchiks: outrageous transgressions on property rights (google CEQA some time), confiscatory taxation, and on and on. But enforcement of criminal statutes and traffic laws isn't one of those areas, by and large. I just don't see it, and I think you've misidentified the enemy, confounded the still legitimate functioning of the government with the less visible, but more invasive intrustions into what should be the private sphere.
That's not to say that there are not problems with modern law enforcement, there are. Kevin Gaines, Rafael Perez et. al. are examples of what can happen when PC goals interfere with (some say lower) standards of integrity for hiring and promotion. But that's a completely different kettle of fish than addressed in these recent posts.
