“It noted that fewer than 1 percent of the more than 30,000 passengers a year who are identified as suspicious end up being arrested, and that the offenses (like carrying drugs or undeclared currency) have not been linked to terrorist plots.”
People smuggling diamonds, drugs, and currency are NOT a terrorist threat to an aircraft. They do NOT want to fly the plane into a landmark. They want the flight to get to its original destination safely, on time, and in one piece.
TSA causes 300 arrests a year for non terrorist reasons at a cost to the taxpayer of $500,000 per arrest.
