The asshole threw a second punch - and he was going for more. You can't go call the freaking cops WHEN YOUR GODDAM FACE IS BEING PUMMELED IN.
Holy jezus, do you even hear yourself when you talk?
Yes, and I've been in bigger protests than that, and in more danger. What You fail to get is the damage that is done to others as a direct result of your actions. You defeat your cause by blemishing it. The Protester did invade space and antagonize, he was wrong there, and at risk. He was still the victim at that point, and would have been seen as a hero for his side, had he not bitten off Grand pa's finger. It's just not done. These protests are going to be getting bigger. It is real important that we do not start massacres. Think Wounded Knee. No Excusses.
