Now, I understand that mistakes happen...Sometimes people hit the wrong key when entering data....sometimes they are tired or distracted or whatever.
But really, no one caught the fact that "Tsarnaev" might also be spelled Tsarnayev"? No one bothered to look at a guy who spent 6 months in training on how to blow people up?
And they spend all that time defending the integrity of their lists...even when completely (and obviously) innocent people are inconvenienced by being on it.
Sometimes incompetence is hard to tell from maliciousness. Especially in a bureaucrat.
