I hope I don't need to say this, but: I don't think Obama should be killed.
That said, I've got to wonder: Is this the lamest assassination attempt ever? With HIV infected blood, you have to 1) open the envelope (which the president, of course, will not do himself anyway), 2) handle the blood, 3) have an open cut or orifice near the blood. And even then, HIV exposure does not equal AIDS. And AIDS does not equal death--certainly not immediately, possibly not for decades. Come on. I don't want to diminish the seriousness of this, but this is just about the stupidest assassin ever.
