They are mortal. They do what they do because they do not fear consequences.

This has been two statements of fact, with no implied conclusions or sub-text.

They’re a part of the rapidly expanding world of so-called less lethal weapons, named such as they are because they are ostensibly less likely to send you to the ancestors when used against you. These weapons come in many different varieties, ranging from “smaller” 9 mm rounds designed to be fired at a person’s legs or torso, to the much bigger, pop-can-sized 40 mm rounds that are designed to be “skip fired” by ricocheting off pavement or other hard surfaces towards their target (police historically do not do this, and simply fire at the target).

I do not for one second buy that they were “designed” to be bounced off the ground. It’s an idiotic concept from the get-go: it’s hard enough to aim a conventional firearm. Expecting any kind of accuracy from a ricochet fired by an untrained and easily frightened moron is a fever dream. Fucking no one expected rubber bullets to be bounced into people’s legs; it was always an excuse for pigs to shoot into crowds. The casualties are a feature, not a bug.

In the US, there is a history of white performers using blackface to play caricatures of black people, leaning hard on racist ethnic stereotypes. From Wikipedia:

The minstrel show, also called minstrelsy, was an American form of theater developed in the early 19th century.[1] The shows were performed by mostly white actors wearing blackface makeup for the purpose of comically portraying racial stereotypes of African Americans. There were also some African-American performers and black-only minstrel groups that formed and toured. Minstrel shows stereotyped blacks as dimwitted, lazy, buffoonish, cowardly, superstitious, and happy-go-lucky.[2][3] Each show consisted of comic skits, variety acts, dancing, and music performances that depicted people specifically of African descent.
