I wholeheartedly agree that the fundamental issue is the complete lack of judicial accountability. These people are getting paid a salary while they harass you, clock out at 5, and their morning routine is to get right back at it. Meanwhile your entire life is personally disrupted due to their power trip and/or malicious mistake, and the best case you can hope for is to be able to walk away?
Whether or not these officers' actions were in line with official department policy, there should be automatic compensation to the victims for their arrest and imprisonment, emotional distress, hiring attorneys and other expenses incurred. And if these officers' actions were not in line with written department policy, then they need to be treated as private citizens harassing people under the color of law, and be held personally criminally liable for the false imprisonment, etc.
