Issues: (1) Officer Safety - Won't that throw off the balance of the pistol and screw up an officer's accuracy in a a life or death situation?
(2) Citizen Safety - Won't this encourage officers to draw their weapons so that they have video evidence of the events at a scene? And a drawn weapon, even if only meant to video the scene, increases the likelihood of something bad happening.
Suggestions: Build s small camera into headgear or to be placed on the shoulder (you know, where everybody used to keep the mike before earpieces became the way to go).
