Let's be clear about something: Rudy Giuliani never tortured anyone. I refuse to believe that the pre-Gonzales US Attorney's office would allow something like that. And hell, just saying it might give those mobsters grounds to appeal their sentences. But it's equally clear that the state of GOP politics is such that Giuliani believes he can gain votes by making dog-whistle appeals to the sadist crowd. And, sadly, I bet Giuliani is probably right about that.
I don't know what kind of person brags about torturing someone when they clearly could never have done anything like that.
