According to the Transportation Security Administration Air travellers in the United States will soon be allowed to carry small scissors and tools on planes, but will face more random security searches that focus more on detecting explosives at airports as part of an effort to thwart potential terrorists.

The new focus on random searches will include more additional screenings of passengers and their bags at security checkpoints. While in the past passengers have been selected for extra or “secondary” screening when they check in for their flight, that will be expanded to checkpoints as well. The secondary checks will be based on behaviour patterns and a random pattern selected by the screeners.

TSA screeners will also use a different pat-down procedure, to improve their ability to detect nonmetal weapons and explosive devices that may be carried on the body. Pat-down searches will now include the arms and legs. But oh, none of this is supposed to cause any major delays.
