A comprehensive resource for safe and responsible laser use
It is not known if the pointers damaged the drone's camera, rendering it unflyable, or if the operator could still fly the drone but decided to land it.
A video posted by Perseus999 includes this commentary from him or her:
This is the moment a police drones is being forced to crash and land by protesters in Chile using simple pointer lasers to blind the drone.
These protesters didn't use any physical or gun force to bring the drone down. Instead, they used another form of technology: lasers. A lot of bright green laser beams were pointed in unison at the drone, which can be seen moving erratically, before quickly falling down to Earth.
A few theories about how the drone was brought down by the lasers are floating around many social media. Some believe the lasers are powerful enough to melt the plastic on the drone if it is a cheap drone. Some others believe the lasers' lights would blind the drone operator's vision through the camera, and the drone would go into autopilot mode and land as a failsafe. Others think that with that many lasers pointing at the drone, it would overheat and malfunction. Speculations that between 40 to 50 lasers were being pointed at the drone have circulated online, and the video certainly demonstrates that these estimates may be true. If that is the case, that's certainly enough lasers to blind the drone's camera lens.

COMMENTARY FROM LASERPOINTERSAFETY.COM: The overheating theories are probably incorrect. Cameras are known to be sensitive to laser light — often much more sensitive than human eyes. So the camera sensor could be damaged, or even if not damaged, causing glare making it difficult or impossible to safely fly.

On March 20 2018 a police helicopter was illuminated by a purple laser beam for about one minute. The pilot had eye irritation and put on night vision goggles. Silva, 33, was located on Fiesta Island and was arrested.
At trial, Silva told the jury he thought he was aiming at a drone piloted by a friend, and stopped when he realized he was instead aiming at a helicopter.
Prosecutors pointed out the difference between the helicopter and a drone, saying "He knew what he was doing. It was intentional. He didn't think he'd get found."
Silva's attorney noted that the helicopter was four miles away and thus looked smaller. She said "malicious intent" was required to convict, and that Silva did not have any intent to harm. She said "he profusely and repeatedly apologized" to police during his arrest, and that police did not go to look for the drone operator.
The jury deadlocked after four hours of deliberation on January 16 2019. Nine jurors voted to acquit and the remaining three jurors voted to convict.
The judge declared a mistrial and ordered Silva to return in late January to schedule dates for a possible re-trial. Silva remains free on $25,000 bond.
The accident happened in mid-October, in Stouerport, North Westchestershire. Simon Evans, next door neighbor to the family, had prior experience operating drones. Oscar was in his family’s front yard when after about 60 seconds of flight, Evans’ drone hit a tree, went out of control, and sliced through the toddler’s eye. The BBC quoted his mother, Amy Roberts, as saying “What I saw was what I thought was the bottom half of his eye, and it's the worst thing I've ever seen."

Analysis and commentary from LaserPointerSafety.com
Although this severe accident did not involve lasers, there are some comparisons and contrasts with consumer laser pointer eye injuries. In almost all cases, a consumer laser injury does not cause complete loss of vision. It certainly does not result in exterior damage or destruction of the entire eyeball. On the other hand, drone injuries are rare, with only a few cases of persons being injured by falling drones. This is the only drone eye injury we are aware of, while there are a number of laser pointer eye injuries, some of which are in lists here and here.
- In Vancouver, the pilot of a K.D. Air Corporation airplane reported a near-miss with a UAV when taking off from Vancouver International Airport. Investigators were searching to find the person responsible. A Royal Canadian Mounted Police spokesperson said this was not the first case, and they have investigated several complaints of model aircraft flying near the airport. According to the Vancouver Sun, he also said that “lasers pointed at police helicopters and other aircraft are equally troubling and there are few regulations prohibiting the use of either device in such situations.”
- In New York City, a UAV described as a “drone” flying near the George Washington Bridge came within 800 feet of a police helicopter. The UAV was at about 2,000 feet altitude, which is above the 400 foot limit set by the Federal Aviation Administration for model aircraft used for recreation. The helicopter pilot was able to track the drone as it landed. Officers on the ground arrested Wilkins Mendoza, 34, and Remy Castro, 23, and charged them with reckless endangerment.
