I would ask the officer what kind of Drone the officer owned and if he would like to fly sometime. and then I would say "sure I guess so, my app says so" What else should I do? even if I was flying without it (and I wouldnt), They have no way of knowing that even if the Drone was in their hands. I would have to teach them how to find it.
A local police officer has no way of knowing if you have remote ID nor do they have the equipment or training to use it.
Name 1 instance in where the authorities used RID to find the owner of a Drone and confront them while they were flying. There are non because its really not possible..Unless you have a chain of RID readers every quarter mile or so everywhere and a Budget that allows you to pay thousands of employees to watch this equipment. The myth that the airport tower can see you or that somehow the local tower can pinpoint your location and I.D. you by the number is just ridiculous if the government ever decides to do that, You will be strapping a Transponder onto your Drone not an RID module.
and again a local police officer will only ask for your TRUST card, that is all they have the authority to do and they know if you dont have it they can ground you.
RID Spoofers do not hide your ID number.... Nor will they disguise your flightpath. They simply add more Drones around you (or the spoofer device) If the person with the RID app is standing within 200 feet of you! Kinda like RID itself, only you get a lot more range with RID. Spoofers are legal simply because the person you are "spoofing" has to pretty much be standing next to you for the app they are using to see the spoofed drones. If the person walks away the spoofed drones go away and your RID remains on the screen. I don't use a spoofer I simply built one as an experiment a ways back, I also asked about the legality of doing so and there is no law against using them.
I fly legally at all times and do my best to follow FAA regulations.
