I happened to be lucky enough to have residence in the places with the most police brutality in the world.
As a Buddhist, I have no idea how you can respond to violence with peace but also without being slashed. I don't think it's possible. But I do believe if you respond to violence with violence, nothing good can come out of it. My way of dealing with violence is to practice Buddhism, but I understand most people do not have the chance or potential for that.
One thing not just abstract but totally practical is that even if I am going to be murdered here, I still may not call LAPD, cuz that may mean I die even sooner.
