This is clearly NOT an FAA decision, rather the Interagency Airspace
Working Group. In other words, the Secret Squirrels, Capitol Police
(responsible for the last "Godzilla Alert" - run and scream from that
terrifying Cessna 150), and DoD.

DoD already got the approval for direct shoot-down authority without
having to coordinate with DHS last month.

FAA is not in control of this thing, they are just following orders.
