TSA's decision on small knives was a tough but sensible one - Ask the Pilot - Boston.com:
Last week, the Transportation Security Administration (TSA) announced it would rescind its longstanding ban on the carriage of small knives. Effective in mid-April, passengers can once again carry implements with blades of up to 2.36 inches onto airplanes.
The decision has raised the ire of some, including flight attendant unions, who have called the decision reckless and dangerous.
However, if you ask me, this is one of the more positive things TSA has done in a long time, and will make the checkpoint process at least marginally less tedious. That some are opposed to the changes is not surprising, but the backlash strikes me as counterproductive.
