One of the main problems is the media; when things like this occur they always focus on the bad people (that is their job, so I can't blame them), but people who watch/read the news, no matter what background you come from, are afraid, whether it is black people who are afraid of the police or officers who are afraid of black people, and this often times brings violence. Another thing I would like to say is that during protests there is never an excuse for violence, even if someone was killed, all it does is make matters worse, whether it is throwing bananas and donuts at police cars or beating people.
