Seems these systems don’t need to shoot. It has interceptor drones. These can fly into the spy drone, so the rich guy can just claim it was a mid-air collision and offer to pay back the owner if they just identify themselves.

They do occasionally enforce the signal jamming laws. Do it with any regularity in a way that messes up police radio, and they will work to catch you.

The thing is though, if a drone is spying on you the police have to do something about it. And if they can’t or won’t then you document everything and when they show up saying you did something, you tell them “so you found the guy who’s been stalking me via drone?” /S for obvious reasons, but these laws are going to have to change sooner rather than later because there’s a lot going on that technically isn’t legal with drones but can’t be prosecuted by the legal system because of this law.

Add that to the military airspace drones keep violating (not under FAA jurisdiction) and eventually this is going to be a problem that the government can’t ignore.

What about international waters 3+ miles off the coast?

All that doesn’t matter in international waters.
