Is there any situation for which a “smart gun” would be useful, for which a “smart holster” would not be better? A smart holster might be of some use to cops who might lose their carry piece in a massed attack (if three people were to approach a cop discretely and then pounce, they’d have a reasonable shot of disarming him); a smart holster might make their job somewhat more difficult.
Would cops want a smart holster that only malfunctioned 5% of the time?
