What am I supposed to even be shocked about?

1) That 4 officers cannot arrest a single guy
2) That they are using inhumane battong, instead of using a civilized gun (The femoid was even attacking his head)
3) That the guy is not even defenting himself proportionally, and they are still useless
4) That the cop is attacking a random woman filming the scene
5) That the cop attacking bystanders KEEPS ON TRYING TO ATTACK the bystander, even when no escalation of bystander happened

I have no words. I don't even know what should I be angry at first. This is so beyond my comprehension of civilization, that I don't have a mental framework for it.
