The TSA's budget is over $7 billion, but unfortunately it doesn't have much to show for investment (Schneier, 2015 ). Over the years, the TSA has maintained a consistently high failure rate in searching for weapons – up to 95% in some cases. Searching for weapons and bombs can be a tedious task, and I'm sure the number of false positives can lead to complacency. There is a quantifiable reality here that suggests the current system in place is not optimal. Add to this the fact that we have not experienced this type of enemy attack against commercial or private aircraft since September 11. One could argue that this is due to the increased presence of the TSA, or perhaps more due to better intelligence, interagency cooperation, and a more vigilant society. Planes have been targeted since September 11. Richard Reid, the "Shoe Bomber", was disrupted by passengers and flight crew. Attempts to use liquid bombs were thwarted by good intelligence. More recent attacks have been of the "lone wolf" type and gunmen hitting soft targets. All terrible acts, but not exactly the same assets that were targeted.
