^^ Good article. I think the main take away point from the incident itself, and also this article, is that the people in charge are completely incompetent. Starting with the DHS all the way down to the TSA - idiots are in charge, and they're not going to catch anyone, and annoy everyone.
As a friend of mine said: "If we can't catch a Nigerian with explosives in feminine underpants, whose father alerted the U.S. embassy, whose ticket was bought in cash, who didn’t check bags, whose visa was denied by the UK, who studied in Yemen, whose name was on a watch list, who can we catch?"
And that pretty much sums it up.
