Demonstrations must be dignified and nonviolent, as the overwhelming protests in Ferguson and Staten Island have been. Do not confuse anarchists who don't want the system to work and thugs who want to exploit a situation with the majority who from day one have operated with impeccable nonviolence and clear goals.
I was cocky and arrogant when I was younger. I thought that if I delivered a good performance, and put my best foot forward, that would be enough to get people's attention. So in my naivety, I cut my legs off at the knees, because I didn't realize that oftentimes it doesn't matter about the performance... it's the media that creates stars.
