Wasn't that the FBI? If there were other means (blank-cheque warrants) to achieve their goals, it seems unlikely that the NSA would loop those agents in. Plus, would evidence obtained that way, without a warrant, even be admissible in any court? I mean, I guess this all went down after Snowden had left the country? So I'm not sure a court date was the end goal anyway. I'm fuzzy on the details/chronology.
