Nothing I said denies the danger of corruption among U.S. police, but truly, as someone who has lived in Mexico since nearly two decades ago, I can concretely, with no doubt in my mind say that police departments and officers down here (as well as the military, though to a lesser extent) regularly, actively engage in levels of corruption, violence, criminal collusion and ineptitud that would put American police to shame even at some of their worst. If you're an American resident, you really don't know of the privilege you have, even with your police at their most mediocre. Sure, they could improve enormously and some departments or officers are deeply, dangerously corrupt, but for the most part, in most places, they're at least not actively criminal in their conduct. Here they are, with rare exceptions to the contrary, even for very basic public security responsibilities. Just two weeks ago in my city a woman known to my circle of friends was beaten and threatened with murder for no reason other than parking next to a patrol vehicle and being questioned by the officers about whether she'd been drinking or not (she hadn't, she was just on her way home and wanted to buy some snacks at a store). This isn't even close to an isolated case. It happens with a frequency that goes way beyond the typical among U.S. police departments of any kind.
