Brown has equipped the glove with a high-powered stun gun, for the sole reason of allowing you to electro-punch shit. To accompany that, he also threw in a flashlight (to better see what you're electro-punching), and a laser pointer (to better aim your electro-punch), and a goddamn video camera (because no one on earth would believe you just electro-punched a dude unless you immediately got that shit onto YouTube).
At some point, a man looked up at the sky and said, "I need to turn this into a punch."
The thinking behind the BodyGuard is that in the heat of a violent encounter, a normal handheld weapon can be easily dropped or taken away -- whereas the only way the BodyGuard can be removed from you is if you were literally disarmed.
Although a relatively new product, the BodyGuard has already gained a measure of interest and fame among law enforcement, and is currently in trials with the LAPD. However, its original use was very different: It was invented to punch mountain lions.
Oh yes. Brown got the idea for his lightning combat glove when he learned of two bikers who had been mauled by a mountain lion. We can't help but be impressed by a guy whose instinctive reaction to such a story is: "I must now punch that lion with thunder!"
There's a certain elegance in simplicity.
