If they refused, they'd be talking about it as a PR move. The most likely possibility is they did hand it over, and the court order included a gag clause preventing them from talking about it.
The order was a doozy, by the way -- everyone within a 17 acre area surrounding a murder scene, including businesses and residences. That's a pretty large dragnet.
