And a better way to detect bombs would be through the use of explosive detecting dogs. They'd be less intrusive, more effective, cheaper, and there'd be no need to make everyone go through scanners that, as the author said, can't tell the difference between C4 and a block of cheddar cheese.
Customs (actually, the Dept of Agriculture) uses dogs, and they are cute little beagles that are very inoffensive and would not provoke anyone. They are looking for biologicals.
I think it’s stupid to make Spanish grannies throw away the chorizo that they’re bringing to their families in the US, but that’s a different matter. (US policy on this should change...why can’t a national of another country bring in a few ounces of some local delicacy?)
However, dogs are excellent at detecting anything, and in addition, Muslims hate dogs...so I say, bring on the dogs!
