This is awful.  I had an acquaintance in Boston who got clubbed in the head by a mounted cop during an anti-Nazi protest.  (The Nazis were going to disrupt a holocost memorial service.)  The Nazis were protected, and the anti-Nazis were clubbed.  Go figure.

By the way, I do tend to read a lot about war, ancient and modern, and against anyone mounted, it is best to form into tight groups.  Horses resist charging into tight masses.  (It helps if you have spears, but that would probably be a felony.)
