It sure takes a whole lot of guts to be part of the riot police as you have to keep the mob at bay without causing serious injury in the process. Thankfully, there have been inventions that make this job easier, and this flashlight is the latest in a long line. Capable of inducing nausea at whoever it flashes at, this works great when you want to disable a target from a safe distance. It utilizes a range finder to measure the distance to the target’s eyes, adjusting the energy level of the light to a level that won’t cause permanent damage followed by shooting pulses of light rapidly from an array of ultrabright LEDs to incapacitate a person. Sounds a whole lot less painful that a water cannon.
