That said: it's increasingly evident that they're very poorly trained. You see the same strongman tactics in every city. They gang up on a single person, sometimes 4 or 5 of them, all hitting, all kicking, and continue to do this once you're on the ground. If you've ever watched Live PD, you see a ton of this same behavior, all the time, all across the country.
At the same time, there are some really bad cops out there (and the cynic in me tells me they're more common than we're lead on to believe), and also lots that just don't have the mental fortitude to do the work, but are still doing it anyway. Those people need to be weeded out, and we need to better equip them with tools that are not weapons.
