When this kind of thing happens in Israel, they prefer to capture the terrorist alive. Then they learn how he was recruited and by whom. Where and how he got the money, guns, and ammunition. What methods of communication where used. They get all the information they can gather about everyone involved in the chain of events, to prevent other attacks.
However, in this case and with the Hussein administration, it is much better that they killed him. I have absolutely no faith whatsoever that Obama is serious about fighting Islamic terrorism. And I say that Obama is not interested in 'Islamic terrorism' specifically, because all he can seem to talk about is some mythical 'home-grown right wing Christian extremists' who are the 'real terrorist', which is just some story that he made up in his own head.
He's going to get even with those damned Christians, no matter what. They are the 'real' problem. Christians are the 'real' evil in the world. Somehow the fact that Muslims are currently slaughtering Christians, and basically everyone else they come into contact with, all over the world, does not matter to Obama.
And even if they did capture the terrorist and attempt to question him, he would immediately have 25 ACLU lawyers to defend him, and would likely end up suing the prison if his pillow was too hard, or his food was not warm enough, or if he was unable to get Al Jeezera on his 50" LCD television. Oh the huge manatee!
America under Obama has transformed from a great world power into an obsequious, needy, high school outcast, who is constantly begging the Muslim world for their approval. As such, our friends no longer trust us, and our enemies no longer fear us. And the worst part about this is, they are absolutely right.
