I think we need to investigate everything. We need investigations of the investigations of the investigations of the inquiries regarding the things they want investigated. We should leave no stone unturned, even if it means a forensic analysis of every rock in the Mohave Desert. The investigators should have complete unfettered access to everything, including Area 51, every secret room at the Pentagon and CIA and NSA Headquarters, as well as that warehouse that they showed at the end of Raiders of the Lost Ark which has all that stuff in it. This should be a complete and comprehensive investigation. Something is bound to turn up.
