Although the Kel-Lite in the 1970s appears to have been the third flashlight designed specifically to be useful as an emergency defensive weapon, the best-known example is the large, metal D-cell Maglite, still in use by some law enforcement and security personnel. Use of such flashlights as a club or baton is generally officially discouraged by the manufacturers and law enforcement officials, but its use is an option. As with all police weapons, there have been many examples of misuse, such as in the Malice Green beating in Detroit. The use of flashlights as improvised impact weapons is subject to the same use of force regulations as the use of purpose-designed impact weapons like batons.
