It could very well be that Tesla'd IT is working to ensure everything is secure amd backed up before they bring in the heavy hand of the law. I wouldnt trust law enforcement to come in, not just seize hard drives for forensic analysis without having a copy to 1) continue work and 2) inadvertently alter evidence. DOJ method is remove drives, that could you affect production or development depending on the drives removed. Either one could be a huge cost suck.
