Whitehead can't have been the first person that Spitzer had "a passionate conversation" with, so maybe this will encourage others to come forth. These sorts of stories have a way of snowballing.
You're right. Though I'm depending on some fellow NY Freeper to remember the particulars. I know Spitzer made a threat to a NYC radiojock on a live phonecall, but I can't remember the radio guy's name or the circumstances of the call. Need some help here.
