Are The TSA Body Scanners Fatally Flawed?

Maybe:

Casey Chan is unimpressed by the TSA's response:

The official TSA blog responded to what the TSA called a "viral video about body scanners" that "is a crude attempt to allegedly show how to circumvent TSA screening procedures." Oh, okay. That's where you expect the TSA to refute the claim that you could fool the body scanner right? To prove us internet folk wrong! To shut everybody up! To keep peace! To curb terrorism! Nope. The TSA didn't do that. At all. Instead they ducked the whole fiasco with this non-denial non-statement statement

The Guardian hears mixed messages from experts. Here's a spokesman Manchester airport, where bodyscanners are used if a passenger sets off the metal detector:

Of Corbett's experiment, spokesman Russell Craig said: "He's taken a small metal tin through. And the guards are looking for a threat object. That's not one. It's not a valid test. To say this shows it undermines airport security technology is totally wrong."
