Couldn't agree more.
I don't know what transpired prior to the beginning of the video. However, when informed that the RNAV (GPS) 11L was unavailable due to LAX departures, the pilot had other options besides throwing a temper tantrum and then employing the tactical use of emergency authority as a means of extortion. One might suppose that he could have held at the IAF until LAX could arrange a pause in departures, but that might have required more fuel than he was willing to burn. He also might have just diverted to somewhere nearby, such as LGB (Long Beach). Aside from that, I am not certain why he would not accept 29R. My Citation flying was limited to the 501 and 550, so I can only speculate that in a 560, 5000' @ sea level is enough pavement even with a 10kt tailwind.
