Actually, the DA did NOT do the deed. He was kept in the dark. Actually, it sounds like the DA is protesting too much.
He could very well have known, and approved and is merely hanging an underling out to dry.
OR... he didn't know, and wasn't trusted to know.
Only two possibilities I can see.
Perhaps he got frustrated about the knowledge that SH is ready to unleash sleepers here to kill many millions and paralyze our cities. So he has changed camps deciding that attacking Iraq would be deadly, but can't say so out of fear of panic in the cities? perhaps he saw what they had when he was kicked out in '98 and had a change of heart and strategy shortly thereafter, his sexual proclivities notwithstanding?
There's something very fishy about this whole affair in that noone is talking about what they are going to do to us.
