It is apparent the guy was under the influence of something or had mental illness issues, or both.  Again, someone slips through the system despite warning signs at LAX, just another in the sequence of events that could of ended up as a disaster that could have been prevented.  How many times have we heard authorities were aware but decided to let the guy go anyway.  Additionally, if true, it was said the guy was of Turkish ethnicity and was carrying a laptop.  Those could be reasons for more attention to the matter.  The ANG, without clear information about the attempted cockpit breach, had to err on the side of caution and scramble fighters in the event of a "worse case scenario".  So, at least they were on the ball, because if they had not been and the aircraft was commandeered and used as a weapon somewhere, there would be hell to pay.
