Obvious from flying that these TSA thugs don't screen myriad weapons from commercial planes. I've inadvertently brought several items aboard that on paper were restricted. A 91 years old relative inadvertently brought a loaded WWII 45 automatic on a trip from San Francisco to Salt Lake.
Seven cigarette lighters can be brought on board per passenger, courtesy of the tobacco lobby. If the bored TSA don't really stop hijackings, what are they for?
Obviously to keep population cowed and feeling powerless... and maybe to give false impression of safety, despite U.S. military sending drones killing people, often women and children, around the world. You kill other people's children enough, maybe you shouldn't be feeling so secure.
Think of all the social good that could be done in United States and around the world if the wasted "security" billions were put to good use.
