Ok lets all take a step back in time to see what caused the vaunted

TSA to insist on body scaners.
It was the underware bomber.
Now lets look at the FACTS on his case that is used for justification for this non-sence.
1. He flew from a known hostile/hot bed of terrorist activity.
2. Bought a ticket WITH CASH ONE WAY
3. Going to chicago without a coat in winter
4. No luggage checked in.
This set off enough red flags (even under the old system) to cause a security officers head to explode.
But the last item is in a whole another case of SUPER RED FLAG.
HIS OWN FATHER TURNED HIM INTO US ATHORITIES AS A RADICAL "NUT JOB" .
The first 4 are stupidity/failure to follow proceedure in a class that normally is criminal gross negligance (at the very least).
The last one alone trumps the other 4 together by a magnitue of 10.
Together it makes pearl harbor and 9/11 look like someone leaving the keys in their car by comparison.
Then it came out in main stream media these body scanners would not have detected this attack anyway.
Lastly the guy who made these things mandatory has a controlling interest in the company THAT MAKES THEM.
So given all the failures of following BASIC SECURITY PROCEEDURES how again do these things help us?
