TSA - TSA announces new airport bomb detectors - The TSA has announced that the busiest U.S. airports (about 40 percent of them) will have "puffer machines" installed by spring. These bomb-detection devices will allow efficient detection of bombs on passangers.
This is a prudent decision for the safety of the nation. The more effective the security systems in airports are, the more oppurtunity the nation has to be secure (at least in domestic skies). Installing these machines would, as the article describes, make bomb-detecting profoundly more efficient, enabling the airports to function more safely.
