Perhaps because this incident WAS safely resolved by peer intervention? Not to say that's the only safeguard. Pilots face "with cause" testing which already goes way beyond other safety-critical personnel. There's no testing whatever, random or otherwise, for surgeons, doctors or medical staff -even if they made an error resulting in a patient death. Nor would a UK police officer face mandatory testing even if he'd just accidentally shot someone.
