I missed this when it happened. To see it play out more than validates the critical posts above. Security was totally AFU. At the time, were they contract, DOD police, or Federal Protective Police? I am thoroughly shocked at the response.
I was a bit surprised that it seemed like the Tactical Flight Officer had a hard time tracking the suspect. Most CHP and CA large muni airborne crews are highly skilled at these sort of things.
I was glad the helo crew landed. Lots of units, especially muni units, are not allowed to land and assist. In my agency, we would land and the Tactical Flight Officer would get out. The pilot NEVER got out, and some of our volunteer pilots were not even armed. Here we saw both crew get out. And, they got out pretty quickly after they landed. When one of the crew walked back to the aircraft you can hear him say on the radio they were going to shut down and be there awhile. So, apparently, the pilot got out and left the aircraft turning? The helo guys here know that I takes a few minutes to allow for cool down and rotor to stop turning (if you don't have a brake, which CHP likely does not).
