I don't think that anyone is denying that liquids can pose a threat. The article stated that by allowing everyone to bring some small amounts of liquides defeats the purpose almost completely. All I would have to do is get 5 of my co-conspirators to carry on 5 little contains each of some volatile liquid and when we get past security we pour them all together to make one big batch of nastiness. This example, and many more, is why we say the TSA's security rules are useless and arbitrary. About the only way to ensure a risk free flight is to force everyone to fly naked, not allow luggage, remove the cleaning crew, etc... and I don't think there are any airlines that are willing to go that far. :/
