Everyone hates the long security lines at airports, but consider yourself lucky that you weren’t in Las Vegas last Friday, where almost the entire TSA shift took a break from their duties to hold an impromptu performance of “The TSA Choir.”

Yes, the passenger lines grew longer and carry-on bags filled the conveyor belts as the choir burst into song: “You’ve gotta dance like there’s nobody watching…” While they were singing, there was only one TSA agent at each backed-up lane. Many travelers missed their flights thanks to these dedicated government employees.

It’s antics like this from some of the nation’s 47,000 unionized TSA employees that only strengthen the case for Congress allowing more airports to use private security screening companies – the way Israel has for years. In the U.S., 22 airports use such companies under TSA guidance. They include major cities such as San Francisco and Orlando, medium-sized cities such as Kansas City and Rochester, N.Y. and small markets such as Key West and Sioux Falls, S.D.

Last week, TSA’s Acting Administrator Ha Nguyen McNeill told a House committee that “if new privatization schemes make sense, then we’re happy to have that discussion to see what we can come up with.”

Our worry is that what happened in Vegas won’t stay in Vegas and we may see more of these stunts by an arrogant and unnecessary union.
