Pro-democracy protesters in Hong Kong have been using laser pointers to distract police officers and confuse facial recognition cameras.

It’s not a secret that things like lasers and lidar can kill camera sensors. You get an intense beam of light pointed towards your camera, and then the lens focuses it into an even brighter point, frying pixels. But did you know that diffused reflected laser light can also cause this to happen?
