One area with which I struggle conceptually is that with a helicopter that's well marked, you could presumably see that from the ground and identify the owner through just a visual confirmation. Again focusing on the means, as you've suggested I shouldn't, I have trouble conceiving of how you would identify a small drone if it doesn't crash. If there's an incident and it falls to the ground, you can pick it up, find the code, and identify the owner. Are there any tools that law enforcement would need to identify someone who is being mischievous with a UAS?
