Well, they have never been able to document a single terrorist attack which they have prevented, not even to classified committees which have asked about it.Unit74 said:How much stuff do they actually catch? Much, much more than you could ever realize.
Their are many reasons to believe this type of mass screening just can’t work to prevent very rare events. The odds just are against them. It is statistically similar to the problem of trying to screen the population for a very rare disease.
Overall, no credible evidence they prevent terrorist attacks. I’d be happy to see some, but the studies that have looked at this say the TSA is not an effective way to save lives.
