More than two years have past since the Chris Brown-Rihanna incident.

Though Brown and Rihanna are collaborating on songs now and are reportedly spending more time together, the court of public opinion doesn’t seem quite ready to forgive him just yet. And, from all indicators, forgiveness appears to the farthest thing from people’s minds when thinking of Brown. Is it that people are being too hard on him or are critics justified in their belief that he has not truly changed?

Experts cautioned that Rihanna, 24, should look for warning signs — if Brown, 22, becomes controlling, jealous or aggressive toward her, verbally or physically.

Rita Smith, executive director of National Coalition Against Domestic Violence, said she didn’t believe Brown seemed that reformed, judging by his reaction to fan criticism and media scrutiny of his performance at the Grammys.
