Startup idea: combine the two! Personal gun cameras with high speed photography on the trigger pull that can be used to exonerate lawful shootings and conveniently deleted if not. Maybe use machine learning for that.
He of course fails to consider that this will simply make guns more un-affordable from the poorest Americans. Those people tend to live in the worst neighborhoods where police respond poorly, and therefore often need them most.
Too late?[0,1] PGFs (Precision Guided Firearms) will take a picture, and help you aim too. They even have apps for your iPhone. Like how CA has a tech focused start-up culture, TX has something of a gun focused start-up culture [2]. IRL aim-bots have been around for ~6 years now, though those companies tend to snatched up by the DoD pretty quickly, so it's tough/expensive to acquire.

[2] Can MA give us an education focused start-up culture? Maybe NC a health care focused one?
>The IVAS Prototype Project seeks to provide a HUD 3.0 and integrated STE Squad capability within the Squad Architecture in support of Army, Marines, and Special Operations Forces within 24 months. The PPA shall deliver a baseline standalone STE Squad capability within 12 months, and STE Squad capability integrated into HUD 3.0 within 24 months. This complete IVAS capability shall be suitable to begin production as early as 4Q20 to ensure clear overmatch in Close Combat engagements and drastically increase Squad Lethality.
That method does not handle factors that cause the bullet's trajectory to not be perfectly straight or flat, such as wind, gravity, Coriolis Effect, etc. They're generally sufficient for short range shorting, but at longer ranges a large part of the skill comes in being able to adjust your sights to compensate for those factors.
Gun sights are also somewhat ineffective because they are only usable from a single position. You can't point the gun around a corner or lift it over the top of something you're hiding behind and still use them unless you expose your head as well. This method would change that and might give you some kind of a camera feed to a HUD that shows where your bullets would hit.
Not useful for civilian life, but I can understand army interest in it.
