There is never a good reason…
…to hit a woman. To hit anyone. Domestic Violence is a problem that should never be justified, for any reason. I don’t care what she did, a man should never hit a woman.
Did Chris Brown hit Rihanna? It seems so, yes. But what ever rumor that is currently being spread as to *why* he hit her is all beside the point. CB hit her hard enough for her to end up with visible marks and scream loud enough for someone to be concerned and call 911. End of story. He should be prosecuted. She should not be blamed. She did not ask for it.
