http://www.msn.com/en-us/news/world/turkish-airlines-plane-diverted-to-canada-after-bomb-threat/ar-BBniV0M?li=BBnb7Kz. Once again a plane is diverted because of a bomb threat, and of course, no bomb is discovered. When I was a kid I remember being evacuated from school more than once due to a bomb threat telephoned in to the school, and of course, no bomb was ever found. I know that authorities feel obligated to treat every threat seriously, but seriously, has there ever been an actual bomb detonated after a threat was received? If you wanted to bomb a plane, a school, a business, etc., you would not give prior warning. Terrorists want to create terror and clearly blowing up something full of people creates more fear and terror than blowing up an evacuated plane or building. Is the automatic response to a called in bomb threat just a form of political correctness, where authorities are more terrified of being accused of failing to act than they are of inconveniencing everyone? I wonder if some school official, when getting that phone call saying "There is a bomb in the school ready to go off" ever just said "Sounds like bullsh-t to me" and hung up, ending what obviously was a prank.
