The radioactive material narrative would require ground teams to move in and secure any radioactive signals, because flying drones cannot do that. There are reported radioactive signals in NYC that no teams have investigated. Therefore I consider that narrative disproved.
HR8610 is up for a vote to re-authorize the 'Orwellian' current FAA authorization. The panic and outrage of the public will pressure legislators to pass that bill, and has already spawned even more draconian legislation. That remains the only narrative that has not been disproved, AFAIK.
Thanks!
