when i was going into my senior year of engineering school a couple of people presented the concept of adding palm or finger print recognition into the grip of a law enforcement firearm to prevent it from being used against the officer should it be taken from him. other than the obvious reason of a misaligned grip rendering the cop's gun inoperable, the university didn't want any part of a gun related design project on their premises.
