Richard Monroe Jr. claims the rapper, whose real name is Calvin Broadus, hit him with a brass-knuckle microphone after he jumped onstage and put his hand on the performer's shoulder.
Broadus sat a few feet away as Monroe described waking up naked, robbed, and in a pool of blood after the beatdown by other performers and the rapper's security detail. A videotape of the incident that occurred at the White River Amphitheater near Seattle was also shown to jurors Friday.
Broadus' attorneys said the video doesn't show the blow to the back of the head that Monroe claims the rapper delivered, nor evidence that the rapper should be forced to pay any damages.
They told jurors during the trial's opening moments Friday that Broadus' security guards had mere seconds to react when Monroe — who stands 6-feet-3 inches tall and weighs nearly 300 pounds — came on stage unexpectedly.
