The only thing that was really sad to see about this was the horses
Cops bringing animals to protests they plan to start violence in is fucked. I feel the same about the attack dogs they sometimes use too. It seems like they bring them solely as some kind of power projection, and in the case of dogs, so they can inflict serious injury without any kind of investigation stemming from it, and with the moral quandary that most people can't or won't hurt an animal
I don't condone anybody harming animals, but it seems like police have animals mainly so they can provoke people into injuring the animals and then yelling about how unfair it is the animals get injured. Also, we aren't in 17th century Britain, don't bring a fucking horse to a protest you archaic savages.
