After the 'shoe bomber' Richard Reid's failed 2001 attempt to blow up AA Flight 63, the TSA modified screening tactics to include passengers removing their shoes for inspection before boarding flights.
Now that the 'underwear bomber' Umar Farouk Abdulmutallab recent failed attempt to blow up NA Flight 253 has come to pass (utilizing the same PETN high explosive as Reid), what new screening tactics should the TSA now implement??
Just wondering.
