Not guilty. That’s the plea Chris Brown’s lawyer has entered in a hit-and-run case against the singer. Brown was charged after a May 12 traffic accident in which he is suspected of rear-ending a car stopped at a red light and refusing to give the other driver his license or insurance information. A trial in that case is set for August 15. Brown was also charged with driving without a license and driving without proof of insurance. Those lesser charges were dismissed yesterday after Brown’s attorney presented proof he was licensed in Virginia – the singer’s home state. Brown’s probation was revoked as a result of the accident – though he remains free.
