An example of this illusion are security checkpoints, and the requirement to discard of all liquids. While people are putting things in trays and having them scanned, lines build, and the wait is increased, and the area becomes more crowded, and throughout this entire process the public is put at a greater risk. Although waiting in long lines does not seem as if it would put us at greater risk, the reality is it does. If a person wanted to set off a bomb all he would have to do is walk to the security gate full of crowded people and set it off right there, causing a horrible scene of devastation. We are forced to discard all of our liquids because they could possibly be explosives; but what doesn’t make sense is that we discard them in trash cans all around the airport. If these liquids were explosives it would be in the public’s best interest to discard them in a private area. Even if the TSA fixed these faults, they still would not be able to stop a real threat. This is because the TSA’s attention is on finding potentially dangerous objects, and their focus is often based on previous threats. For example, if someone brought liquid explosives the TSA would then go through every bottle in every bag prior to the discovery. Focusing on previous threats will not stop new ones from happening, causing the TSA to be a step behind the terrorists. According to Bruce Shneier, a critic of
