The article states that at times it was flying as low as 10' from the ground. At that height a good garden hose should bring it down. Knocking it down with a blast from a shot gun was just stupid... but I like the effect. But he was in his own yard and the drone was intrusive. Ideally, he should get his fingers rapped with a ruler and the drone owners denied any financial compensation. WTH, charge them with public harassment as well, or whatever would suffice.
At the end of that story link was a video news report on how numerous drones were interfering with fire fighting out in California, keeping rescue and firefighting helicopters from safely preforming their duties.
What's the saying about technology... "designed by geniuses to be operated by idiots".
It certainly applies here.
