I'll just drop this here for readers to opine on . . .

The criminal UAV issue is not limited to America by any means. Police in the UK received 3,456 incident reports of drones behaving badly in 2016, a threefold jump from 2015, a 12-fold increase since 2014 and equivalent to 10 complaints a day. The incidents ranged from minor spats between neighbors to covertly dropping drugs and firearms into prisons. A photographer even managed to set his camera drone down aboard Britain's biggest warship, the HMS Queen Elizabeth, with nary a consequence. As the photographer told the BBC:
I could have been anybody. It was like a ghost ship. I would say my mistake should open their eyes to a glaring gap in security. This was a bit of tomfoolery, but it could have been something terrible, not just for the ship and its crew but for the people of Invergordon...

UAVs have also proved quite useful to some of the most ruthless and powerful crime syndicates in South America. Last November, Colombian law enforcement discovered 287 pounds of cocaine as well as a disassembled UAV, possibly belonging to the Clan del Golfo criminal organization, buried on a beach in the coastal town of Bahía Solano.
"The drone was used to carry cocaine to Panama, it had the capacity to transport 10 kilos [22 pounds] on each trip and to travel a distance of 100 kilometers [62 miles]," José Acevedo, the regional police commander, told El Siglo. While the police did not specify what kind of drone was hidden, the fact that it can carry 22 pounds a trip strongly suggests this was a more robust device than the typical commercially available UAV.

However, law enforcement is far from helpless in countering these incidents. Michael Blades, research director at market-research firm Frost & Sullivan, recently told Air and Space Magazine that the anti-drone business is worth "between $500 million and a billion dollars right now" and could grow to $1.3 billion by 2023. "I think double-digit growth is a foregone conclusion," he said, "just because they're starting from almost zero right now."
Counter-drone systems are as varied as they are numerous, ranging from shotgun shells loaded with wire nets to eagles trained to snatch UAVs from midair. Snake River Shooting, an Idaho-based ammo manufacturer, has even come out with "dronemunition," ferromagnetic birdshot packed into 12-gauge shotgun shells. Many counter-drone technologies, however, are far less dramatic and instead rely on radio-frequency jamming to take out the offending UAV. The DoD's Navy Special Warfare Command in July signed a $1.5 million contract with SkySafe to develop a vehicle-mounted RF jammer that can identify, track and disable enemy UAVs before they can get close enough to do harm to friendly troops.
