"He barely even turned around. ... My friend didn't do anything," Mohammad told the Deseret News newspaper.
Scores of police, some of them carrying riot shields, responded to the scene where crowds of angry onlookers hurled abuse, rocks and bottles at the officers. Authorities said four people were arrested for civil disorder. http://www.reviewjournal.com/news/nation-and-world/protesters-hurl-rocks-police-after-black-teenager-shot-salt-lake-city
So, you have a thug who was beating on an old man, while holding deadly weapon.. If you don't think a broom is not a deadly weapon, prove it by allowing me to hit you for 10 minutes at my own strength and we can see what happens.
But once again the black terrorists who threw rocks and bottles at the cops?
Did thug protesters did protest the old man because he was being beaten by a black thug?
Yeah, I doubt it to.
