Whatever's convenient to dispose of people in the way of the status quo. Remember that the feds really started rounding up pot smokers on a large scale for the first time as a way to legally get rid of Vietnam war protestors.

Nobody is 100% law-abiding or morally clean. Nobody. We're definitely all vulnerable to prosecution and blackmail. People who think they have nothing to hide aren't using their imagination properly.
