New Scanners In The Nations Airports?

According to the Transportation Authority they are inserting full body scanners into the nations airports to search people for bombs and other things not meant to be carried around. I think they should have done this when 9/11 happened but they were to dumb to understand that people will try to do it again this isnt the last incident with death. We all know that some people are crazy and will go to extroidinary measures to do extremely stupid and hurtful things to the nations. For example the man that inserted c4 plastic explosive into his butt just to try and blow up the Saudi Prince but he didnt succeed. It just proves that people are mentally insane and dont know when enough is enough.
