Do you truly believe that someone with outstanding warrants would put themselves in a position (like applying for a job for instance) that would require a background check? That aside, the message you are sending then is that airports are some kid of "safety zone"? A felon need only get to CVG and shout "all in free" or something? Sorry, I don't want him on my flight, he's all yours.

And as far as my own background is concerned, take your best shot. I'm willing to bet any amount you like that my background has been investigated to a greater degree than anyone on this board, with the possible exception of Bart.
