Some moron tried to blow himself up on Christmas day. Fortunately he was a moron, and therefore unsuccessful but even morons get lucky now and then. Why do we as a country waste resources screening grandmas and grandpas versus using profiling? This is simple folks, limited resources must be used to target the most likely threats. Clearly looking at everyone doesn't work (as this episode has demostrated) so maybe we should try a different tact.
It just goes to show you, government, regardless of who administers it, is incompentent. Our safety is the most essential duty and they failed miserably. I suppose there's a lesson in here somewhere.
