Of course theres the argument that "even someone who flies a million miles a year with a background check can still do something bad"...but lets face it, this is about REDUCING risk. not eliminating it. There simply isnt enough time or resources to completely eliminate risk, and short of making everyone fly naked and empty handed, there is no way to completely eliminate risk.
