Cops have near impenetrable immunity (qualified immunity), so there's little legal harm to them in walking away when they're wrong, unless they did something grossly illegal and it's on camera somewhere. I think it's human nature - they're in a position of power, their victim must comply with all their requests and any resistance is punishable severely, so they turn into bullies.
