There is an extensive military oriented research program related to using swarms of semi-autonomous drones in combat situations. That cat got out of the bag some time ago.
At this point we can safely assume there will be millions of them in private, public, and military use in the future. Preventing evil users from using them for nefarious purposes will require focusing on the people, the same way that preventing bad guys from using guns requires focusing on the bad guys not the guns.
Trying to ban drones will only mean people in the USA will fall behind in knowing how to make and use drones. We need to lead that effort, not end up huddled in our basements trying to figure out what to do about the foreign made drones that are attacking us.
Think about that -- people in Pakistan cower in their houses as drone fired missiles land in their midst. They don't have the ability to do anything about it. Let's not end up like they are.
We need to encourage research, education, making, selling, flying, and everything else related to drones. So we lead the world in knowing how to use them for good -- and if necessary to defend ourselves and our freedom.
And we always need to deter, disrupt, arrest, and prosecute people that are planning or conducting attacks on the rest of us - regardless of what they are using to do evil.
Often useful to look at a question without “terrorism!”.
A drone flown over one’s own property could be ‘regulated’ like a dog: an id number and owner on record. Maybe you’’d put up “beware of drone” signs. The idea is just for normal insurance purposes. In a rural area like mine anyone would know whose drone it is, but in semi-rural areas a drone could cause damage and the owner may not be identifiable.
A drone used in other’s airspace though would have to be treated like a plane. Transponder, license, insurance, pilot’s license... could skip the physical at least.
These measures also address “terrorism!” requirements to a significant degree.
She mentions tracking the control source. Seems a reasonable request off hand.
