FBI Update 8 Dec 19 - only the US Attorney and the SAC FBI Field Office Jacksonville spoke - nothing new apart from the following official confirmations:
- It has been classified as an act of terrorism.
- There was only one shooter whose identity was officially confirmed.
- All foreign students have been accounted for (there had been some fake news to the contrary).
- No Saudi students are in FBI custody - they have been confined to base by their CO - they are cooperating with the investigation.
- The firearm was a Glock Model 45 9mm and it was purchased legally (again contrary to fake news regarding foreign nationals not being allowed to purchase firearms - there must be some applicable exemption clause).
All other obvious questions were asked but the FBI SAC declined to answer due to the ongoing investigation.
