If you watch the video, the officer was clearly outnumbered and a hostile crowd was beginning to assemble around him. He was perfectly justified in trying to defend himself, because someone in the crowd or the girls themselves could have tried to disable him and grab his firearm.
Those two girls are now arrested and in custody as well they should be. If this had been two white girls fighting with a white cop, there would have been no story.
Even the police have a right to defend themselves against thuggish behavior.
You’re right, if it had been two white teenagers this would not have been news. Having said that, how often do you hear of white people behaving in the manner of those two?
I am sick of the police being blamed all the time. If you don’t want negative attention from the law, don’t break it.
