When a caller alleges an invasion of privacy, or careless and reckless flying, both of which are criminal matters in every jurisdiction, no
dispatcher can properly state that "nothing illegal has happened." The police are obligated to respond and investigate. It may not be promptly, but LEO have the right to verify registration of any drone pilot and collect evidence for the FAA, in addition to investigating any alleged criminal matters. Municipalities are also now creating new criminal muni codes to allow LEO to cite and arrest drone flyers for FAA violations. Don't assume you immune. Know all
local laws, in addition to FAA regs, that you may be subject to, relating to not only where you fly, but how you fly. "Flying under the radar" so to speak, is often wiser than putting a target on your back.
