But the investigation was stalled, partially because of how hard it is to send lidar scans.

Today’s leading cloud storage services — Google Drive, DropBox, iCloud, and OneDrive — don’t support the massive three dimensional files (sometimes, multiple terabytes in size) used with lidar technology. The naval unit in San Diego was forced to overnight thumb drives and Blu-ray discs, containing lidar scans of the charred naval ship, to authorities around the country.
