There's the law and then there's context. Sadly, society seems to be losing its collective ability to note the difference. To watch this is to plainly see the context. He was being nothing in the way of inappropriate. Heck, he was giddy, smiling and amiable, and then playfully pecks a kiss on the side of the woman's head. Sure, the law allows for any physical contact to be identified as assault, but again, CONTEXT.
The world is quickly losing its marbles in so, so many ways, it's depressing.
