I think this is a great idea!
Who better knows how to safely use a gun than an officer, not only handling the weapon, but also all the other factors of owning a gun that you plan to carry around with you in public.
Of course, just like the idiot drivers that took the same drivers test we did, there will be some that won't learn a thing and will be terrible gun owners. But, there will also be a lot of people that will benefit - which benefits us all.
Contact your local law enforcement or politician and tell them you want this.
