True that. But it is also true that plenty of bad conduct is not criminal, and you can bet your bottom dollar that the sociopaths in positions of power know just how bad they can go without crossing that line.
Yes. Real criminologists, not run of the mill academic sociology majors, have a category of ‘criminal equivalent” behavior— to account for those who are hostile, unethical, exploitive, dishonest in all kinds of ways but who stay between the legal ditches and never face a day in court.
