It's a bit strange that they can do that. FBI didn't have a problem grabbing Core IP/Croydon equipment when they investigated the Paypal attacks couple years ago, but here, they somehow can't find some legal justification to force Cogent/Carpathia to keep the data. Isn't it evidence? It pretty much seems like DOJ or whoever wanted to destroy Megaupload and they will have achieved that regardless of how they pursue it. No data, no company, they're still in jail.
