Having seen the video on YouTube it is the most obvious thing in the world.
The full body scanners being used by the TSA in major US and international airports are completely and utterly useless in stopping people from getting on planes with guns, ammunition and any other object.
And not only that, the full body scanners could actually be making air travel less safe because of the complacency they could breed amongst airport security staff (if the staff at airports believe the full body scanners are the ultimate answer).
The video on YouTube is apparently being censored but I encourage you to try to find it so you can judge for yourself whether full body scanners are making air travel less or more secure.
to err is human , to f*k up badly takes a Government.
