The TSA gropes grandmas, children, and senators while the real terrorists are planning new ways to skirt around our ludicrous security measures. The U.S. government has no right to authorize the sexual assault of those who simply want to fly a plane. If the machine picks people at random as Rand Paul suspects the X-ray scanners are useless pieces of equipment. I do think he is correct about that since the first time he went through he was tagged by the machine for a pat down and the second time he wasn't. When something is being used indiscriminately and isn't targeted to the problem, like who may or may not pose a threat, then the machine is doing more harm than good giving people a false sense of security. What a useless piece of junk.
