Laser Pointers & Non Lethal Weapons

The police and military have always tried to limit their responses to crowd control and rioting. They have an arsenal of non lethal weapons such as water cannons, rubber bullets, shotguns that fire bean bags, millimeter wave technology that heats your skin at long distances, high power ultrasonic emitters that make you lose your balance,  pepper spray and Taser guns for close range. Now a new weapon has been added, a laser based device, designed using a  diode pumped, 532 nanometer green output to dazzle people long enough to take action. A company called Laser Energenics has come up with two dazer laser products, the Defender and the Guardian. The Guardian has a range of  1-300 meters and the Defender has a range of 1-2400 meters. They claim both weapons are eye safe beyond 1 meter according to ANSI ( American National Standard Institute (ANSI) safety standard Z136.1) laser safety standards.

It seems a bit Ironic that the US federal government has outlawed the importation of laser pointers with power levels exceeding 5 milliwatts in the name of homeland security yet they allow their own forces to wield lasers.
There are hand held solid state green (up to 1000 milliwatts) and violet (455 nanometer) lasers (up to 2000 milliwatts) manufactured in China that make the Defender and Guardian lasers look like toys in comparison. Even though those laser torches are not permitted to be sold or imported in many countries, they still make it through the mail and past Customs agents. Those handheld, high power lasers are the size of a flashlight and pose a real threat to air traffic, hence heavy fines and prison sentences follow anyone caught interfering with any aircraft. If you do a Google or Youtube search of "How to make a handheld laser torch" you can probably find plans or somebody willing to sell you parts to make your own. Laser are everywhere, so use common sense and beware of deviant individuals who pose a terrorist threat.
