Bluetooth-enabled bullets. So — BLAM — you shoot the bad guy. Then you reholster or just drop (because they’ll be getting cheaper and more disposable — like everything else) your gun, grab your telephone, open the app, and guide the bullet right downtown! Oh, sure, you’ll probably have to pair the bullet before or after the shot, or before AND after, and that’s only after your SmartGun is able to get a good thumbprint and verify that it’s you, which is after the new software update, and the Adobe update...
But if you actually survive the encounter, it’ll be an awesome story, which was hopefully recorded on that guide-rod camera, so you can post all of this on YouTube.
