We are talking about two different people. Key is just a tad discourteous at times. This other guy with the changing name is a real problem. Upload the video, I bet it blows most people's minds.
I saw some stuff (that guy) with BigAirAl one day at NB that was just whack. (I know it might be bad), but no one else was around so we just watched in amazement, waiting for the guy to get injured doing his shinanagins. We were amazed he didn't actually end up in a tree.

In terms of threats, I definitely think most situations can and should be talked out, but about 4 years ago I lost it on a guy who was being a total dumba.## right in front of our most crowded beach hotel about this time of year and wouldn't leave. He was literally repeatedly crashing his kite right on the shoreline and people were, again literally, running out of the way. In hindsight, I wish I would have gone and got the beach police or someone with similar authority.
