Why "OMG the TSA searched a kid" stories are bad, from a Dish reader

Every time there is one of these “Oh my God can you believe they searched a child/old woman/nun” stories, there seems to be the impression that other, more deserving (??) people are not being searched.  Everybody has to stand in line and be inconvenienced; terrorists waving AK-47s are not running past while a four year old is being frisked.  As anyone who has travelled has learned, TSA is not speeding up the process because of a crowd.  Yes, I can point to ten or so people I think I would search more thoroughly while I sit in line for an hour at LaGuardia, but that just makes me a little bigoted and likely somewhat dumb because none of those people blew up a plane.
