Looks like another drone operator flying too close to crowds. It is interesting that the police took the drone operator's side: http://www.sandiegouniontribune.com/news/2015/aug/19/man-jailed-beach-drone-confrontation/ Based on the fact it was brought down by a T-Shirt, I tend to lean towards the beachgoers side. For it to be low enough for that to happen and that close to a crowd of people definitely falls into the reckless category in my book. I have filmed a few events at or near the beach and I always head straight over the ocean at least 50m off shore and at least 40m up. Even the path I take to the ocean I verify is free of people before takeoff. At that altitude and location most people have no clue its even there.
