One guy had the idea for shoe bombs. So now, hundreds of millions of people have to take their shoes off and spread their foot fungus around. Well if we want to REALLY be serious about security, we DID have an "underwear bomber" too, Why are we not checking everyone underwear ?

You can NOT take a sealed can of Pepsi through the security line, but lighters, whips and 12 inch knitting spikes are perfectly fine.

Oh, I almost forgot. How many TSA Agents have been arrested for smuggling, theft, sex assault, drug deals, murder, extortion ?

And we really trust these people to protect us ?
This farce has nothing to do with security. It is about control and the appearance of security. Training people to be compliant. Why is it necessary to do "pat downs" on children, babies (even autistic kids) ? To teach the kids and their families to follow orders. Start young and make them compliant.
