George Leef’s latest column for Forbes probes — no pun intended — problems associated with the federal Transportation Security Administration.

The TSA has an annual budget of $7.9 billion and employs 62,000 people. Its principal function is to operate the passenger screening function at more than 450 commercial airports. Keeping dangerous people off airplanes is unquestionably important, but is it wise to entrust this to a federal bureaucracy? There is solid evidence that the TSA is not very good at this job, but spends a lot of money uselessly.

Exhibit A is the Screening of Passengers by Observation Techniques (SPOT, naturally) program. The idea behind SPOT is that government observers in airports can detect individuals who are intent on terrorism merely by looking at them and discerning behavioral clues. SPOT was begun in 2007 and employs some 2,800 TSA personnel.
