Some posit that the events of 9/11 has made America paranoid, and that the security measures applied at airports are over the top, invasive, and excessive. Now, they might be adding "ineffective" to that litany. The US' own Department of Homeland Security went undercover to put these airport security checkpoints to the test, seeing if they can beat the system that the government has put in place. The results might be shocking for some while expected for others, but worrying nonetheless. Out of 70 undercover tests, the TSA failed 67.
