In recent years the Transportation Security Administration(TSA) has placed new security measures at certain airports that require random swaps of passenger’s hands for explosive residue. This measure was put into effect after the Christmas Day attempt bombing in 2009 of the Northwest Airlines Flight 253. While this safety measure was put into effect for the wellbeing of the American public, it also has the potential to do the opposite. Jay Stanley, an attorney and privacy expert with the American Civil Liberties as quoted by CNN saying: “[The TSA] are basically looking for particles of explosives, which is not something that people normally have." While the average person may not have explosives or come in direct contact with them, this does not weed out to fact that a normal person might come in contact with explosive residue though transfer.
