Via Drudge, NBC Chicago reports that Rahm Emanuel was "taken aback" when asked about his remark "you never want a serious crisis to go to waste."

"First of all, what I said is never allow a good crisis go to waste when its an opportunity to do things you had never considered or didn't think were possible," said Emanuel. "That's not intended for this moment, or does it apply to this moment." 

Emanuel went on to say that Giffords is a friend and that he pioneered the kind of event where Giffords was gunned down. He did not offer any criteria for which crises should be exploited and which ones shouldn't. Perhaps the Emanuel Rule needs to be amended to exclude mass murders from the category of crises to exploit.
