Yes, he's right. It was an assault and battery. Defined differently in diff. states, but a battery generally occurs when you actually touch someone in an "offensive" way. This would clearly qualify. Generally speaking, assault doesn't require that you actually touch someone. Having said that, most cops/prosecutors would not waste their time with this. But if you did what Prince did, on the street in front of an overzealous cop ... yes, you could be arrested for assault and battery.
