Lasers to the Rescue! By Brian Simpson

     Who would have thought that the once-humble laser pointer, used in lecture theatres across the world, could be used by those getting up to such mischief by protesters in Chile. Hong Kong, well, yes, but Chile, well, that’s a surprise:

“As the protests have raged, the repression unleashed on demonstrators has become increasingly brutal and high-tech. Chile’s protesters, however, have responded with a combination of ingenuity, persistence, and equally high-tech tricks to fend off police attacks. Such was the case earlier this week in footage that quickly went viral on social media Wednesday that appeared to show a police unmanned aerial system (UAS) being disabled as protesters aimed run-of-the-mill green laser pointers—the type available in any Office Depot or Staples—at the law enforcement-grade drone. The video, which NextGov reports first made its appearance Tuesday night on Reddit, shows the drone hovering above a sea of demonstrators as the lasers are trained on it. Soon, multiple other lasers are trained on it and when the drone attempts to escape, the lasers have an almost tractor beam-like effect, forcing the UAS to falter before it helplessly descends to the ground. Laser lights at demonstrations didn’t first appear in Chile. The pointers have had a ubiquitous presence at the raucous demonstrations in Hong Kong, where protesters have also used the lasers to disable surveillance cameras equipped with facial recognition technology. And as Defense Maven reports, U.S. Army Stryker vehicles are also being equipped with laser weapons that would be used to disable and knock out incoming flying drones.

However, the consumer-grade lasers at Chile’s protests are hardly the type that can chew through armor or burn through flesh, like military laser cannons might. Instead, these lasers likely either blinded the camera feed of the human operator or disabled the drone’s altitude sensors, triggering the drone’s emergency autonomous landing capabilities. While the lasers have proved effective in such a grassroots, mass-uprising context, some experts say the lasers are unlikely to pose a major danger to drones. Christopher Williams, who heads Citadel Defense Company, which hopes to deploy an anti-drone “bubble”-based system for U.S. Customs and Border Protection along the U.S. southern border, told NextGov: Use of these types of lasers is more hazardous and disruptive to humans than it will be for drones. There are many other technologies that are less disruptive that provide a superior, more scalable, more reliable and more cost-effective countermeasure. For now, however, the lasers designed for office presentations rather than for military tactical purposes appear to be working just fine for the combative Chilean people taking to the streets to demand greater social and political rights.”

     Clearly, laser pointer weapons are as dangerous as firearms and must be quickly banned unless any more poor drones get shot out of the sky, like little lost birdies, falling from the heavens. I remember Marvel Comics Stan Lee, writing “The Last Fantastic Four Adventure,” a story beginning with something like: “When a sparrow fell from the sky, it was the beginning of the end of our world.” Wait, what has that got to do with lasers and drones? Symbolism, mate, symbolism.
