Humanity likes to think it is so far beyond the animals we once were but we really are not.
You realise we are communicating abstract concepts using language right now.
But if you feel closer to the animals. Maybe go live with them and see how that goes for you.
If you don't think humanity can turn violent easily you've not seen some of the bar brawls break out I have lol. Or run into the kinds of people who like to fight for the sake of picking a fight.
I've been very open, on these forums, about the kinds of violence I've been subjected to in my life. I've been put in hospital several times. Friends of mine have been knifed and attacked with bricks. I can't go a week without hearing about some member of my community being beaten up in public, or attacked with acid, or murdered.
When I talk about the violence inherent in the system, I mean it because I've seen it. It's not mindless, animal violence, it's deliberate and calculated. Like crushing a person's neck for over a minute after they lose consciousness. I don't particularly care about people fighting in bars for fun. I care about what those people do to their partners or kids when they need to keep them in line. What they do when they encounter the "wrong kind" of person who they know doesn't have the clout or privilege to fight back.
Even if you believe that humans are inherently violent, the fact remains that the way humans direct and express violence isn't random. It has political aims and political ends. Racist violence isn't random, it serves the political purpose of keeping black people afraid and politically disenfranchised, of cultivating indifference or lack of empathy towards black people's suffering, and ultimately of preserving a social order where some people are systematically denied opportunities so that they can be forced to do shit-work for no money. There is no such thing as benevolent authoritarianism, or a benevolent hierarchy. There are only relative degrees of violence.
People are objecting to non lethal rounds being used (not merely the miss use of them). This should be seen as the Police trying somewhat.
I don't think you've really thought about what "non-lethal rounds" are.
A beanbag round is a lead slug inside a padded cushion. It is fired from a standard shotgun and leaves the barrel at 90 meters per second. It is trivial to kill or permanently injure someone with a beanbag round. A hit to the neck can collapse the windpipe or shatter the vertebrae, a hit to the face can shatter the nose, cause permanent blindness or disfigurement, or even crack the skull. A hit to the ribs can break the ribs and drive bone shrapnel into the heart or lungs.
The journalist who was hit by pepperballs in that video a few pages back (the one who shouted "I've been shot!"). It turns out, she was also hit in the face by a marking round, which burst one of her eyeballs. She is now permanently blind in one eye, and will have facial scars for life.
These are less lethal rounds, meaning just that. They are less lethal than high velocity penetrating ammunition, but firing them indiscriminately into a crowd (or at journalists) can injure or kill people quite easily.
