It makes me damned uncomfortable to think, as I walk down the street, I might be passing someone who thinks the way you do. I'd expect them to have tentacles coming out of their forehead but no, they'll just look like someone on the street. That's scary.
And yeah, torture doesn't work, even if you have the right person (you might have to torture everyone to make sure you get the terrorist with the 411). That's been proven long since.
