Yes, the FBI grabbed, then opened the boxes after judge #1 said that they should not open the boxes. In fact not only did the FBI open the boxes and inspect their contents, they co-mingled the contents of all the boxes such that the boxes original contents could not be determined.

Knowing that the FBI presumed guilt and not innocence, 400 of these customers filed a suit instead.
Judge #2 ruled in favor of the FBI. The Plaintiff is appealing to the 9th circuit.
