LAX -closes over sprinkler bomb scare!

LAX one of the most modern airports in the world today had to close because of a suspicious pipe in a bag.which by the way after an examinaiton by the bomb squad was found to be a part of a sprinler pipe.so one can literally say that "LAX's daily routine was sprinklered on!"
as a result of this scare,LAX shut down certain parts of the airport and made the passengers go out onto the tarmac while they were investigating this matter.what i cannot understand is that LAX is one of those airports with all these high tech equipment which if they had used correctly would have given them the requisite details about the pipe.so they could have avoided shutting down a part of the airport.It certainly made travel by plane a nightmare for many!anyway it is better to be safe than sorry!
