So, I'll add another worm to the can.
You're advocating the right for federal authorities to usurp state or city funded institutions simply because they're feds?
not because they're the feds, but because it's public,open to anyone and paid for by everyone.I don't see why they couldn't get a warrant. it's not like the librarians or patrons were hiding or smashing hard drives or the library was going any where.
