I'm not very smart, but I don't think you need to worry about drones using the linked flamethrower attachment: in order to buy from the website, the terrorist needs to click the "Agree" checkbox that says "I understand that operating a drone or UAS in the US with this attachment would require a Part 107 Waiver."

This page has some information about operating drones over people: https://www.faa.gov/uas/commercial_operators/operations_over... . That page says "the remote pilot must take steps using a safety risk-based approach to ensure that ... the small UAS is not operated in a careless or reckless manner so as to endanger the life or property of another (§ 107.23)". So IIUC, I think it's likely that the FAA would deny the application for the Part 107 Waiver, and the terrorist wouldn't be able to use it.

Hope that helps!

I’m 99% sure you’re joking… but since this is the internet, I’ll say it explicitly: obviously the terrorist would check the box, never bother applying for FAA waiver, and fly the drone anyway.

That would be breaking the law, however, which is against the law.

Much like the beloved US Visa question "are you a terrorist? y/n"
