"Once the feds get involved and people start down the cooperation path, you never know what you're going to end up with," said veteran defense attorney Stanton D. Levenson. "And I think that's what you're seeing. They're moving into areas they didn't know about originally. (Mod Squad, Post-Gazette)

While we're on the subject... remember that public-to-political e-mail lists theory? A new respondent has since reached out to this blog, who has received Wagner campaign e-mails in an account used at, and for, a place of employment over 20 miles from Pittsburgh. That would seem to rule out the exonerating theory of e-mail lists purchased from firms "by zip code". The respondent further denies ever having subscribed to any political campaign through that account, ruling out the other legitimating avenue. But yes, the respondent indeed claims it had previously been used to sign up for e-mails "from the City (of Pittsburgh) and the Mayor."
In any event, ring the City Bell if we learn anything new and conclusive about investigations into our city. ProTip: If you have helped, that bell will sound more lovely.
