Lets be at least a little fair and accurate - "100%" rarely applies in any circumstances. Basic airline security (e.g. x-ray for guns) goes back far before TSA as we know it. So at the very least part of the money spent on TSA is performing a useful function. Is TSA wasting money - sure - its a government agency and government agencies tend to waste money trying to satisfy too many constituencies at once. I'm not really sure if there is a practical/feasible alternative though - by some arguements they could be more efficient applying profiling techniques but that would set off left leaning constituencies. On the other hand their current techniques which try to avoid direct profiling tend to set off the Right leaning constituencies.

By the same token 100% couldn't apply to trying to satisfy the "save america from IslamoFascism" crowd. If they were really 100% committed to such a goal then they'd be strip-searching every "muslim looking" (whatever that is) person that tried to fly.

In the end its just another mixed up government agency. When something big happens I'm sure they'll do what every clumsy large business/government agency does - try to cover up their mistakes with another re-org.
