The FAA considers drones to be aircraft, and it is illegal under federal law to do anything to cause damage to someone else's drone
It's also illegal to interfere/endanger aircraft dropping fire retardant on wildfires or to encroach takeoff/landing areas at airports, but it's being done....with drones.
We have laws that stipulate how, where, when and by whom drones are to be operated and what the penalties are when those laws are broken. We have laws that stipulate how, where, when and by whom firearms can be possessed and discharged and what the penalties are when those laws are broken.
What it boils down to is that we have many, many laws about many things. We also have just as many people breaking those laws....positive proof that passing a law does not prevent a particular infraction. We have stupid people with drone controls in their hands and we have stupid people with firearms in their hands. The twain are destined to interact.
And anyone with the brilliant idea of shooting it down will surely be arrested for discharging firearms within city limits.
"Surely?" I disagree and would say it would be more like "possibly". I definitely am not an advocate of drone-hunting/shooting. I'm just stating an opinion here. I live in the middle of a 180,000 acre national forest about 500 yards uphill from a 21,000 acre lake in a very rural setting. My point? It depends on the location as to whether or not such an action could take place with impunity.
"Brilliant?" Anyone with the "brilliant" act of crashing a drone into my house, my property, endangering me, any member of my family or my pets WHILE ON MY PRIVATE PROPERY due to their recklessness or disregard for the safety and privacy of others will not be pleased with the outcome.
