I do? If they are suspect in a crime for specific reasons, why are those specific reasons not enough leads to follow?
As Chomsky said, if you're so worried about terrorism, stop participating in it... as in, The Iraq "War" alone killed so many more people than 9/11, and nobody could even be arsed to look at the debris of the latter before destroying it. This is akin to a wolf saying the chicken need to tell him where they are at all times, to better protect them. Feel free to fall for that once, but then please join the rest of us in the real world.
