Newton librarian forces FBI to get warrant for computer seizure

The librarian tells the FBI that they can’t seize the computers without a warrant. Nine hours later, the agents produce a warrant for the computers as a matter of principle and take the computers even though they have determined that there was no immediate terrorist threat.
If it [the seizure] was so important, why didn’t they get a judge to sign a warrant to begin with? It was in fact 2:30ish in the afternoon at the moment they wished to make the initial seizure! tsk tsk. It’s amusing that while citizens must abide by the laws of the state, but should those that enforce the laws abide by them also? Perhaps there’s a dilemma here.
