A reader writes, "Boston PD subpoenas Twitter for info on users tweeting about Occupy Boston; they say it relates to a 'criminal investigation'. Also notice their ignorance when asking for account info on tags such as '#occupyboston'. Smart cookies over there."

Note that they're also looking for IP addresses for Guido Fawkes, a well-known, right-leaning British blogger (real name Paul Staines) who -- as far as I know -- has nothing to do with Boston (let alone Occupy Boston). My guess is that they've somehow mistaken Guido Fawkes for some kind of superdistributor of Guy Fawkes masks or similar (the historical Guy Fawkes did adopt the name Guido while fighting in Spain in the the 16th cen), which is to say that they're not just on a fishing expedition, they're on a fishing expedition that's grounded in profound ignorance.

And yup, they don't know the difference between a hashtag and an account.
