Even though some people may hate this, I'd be fine with background checks IF we, as private individuals, were able to call NICS. The fact that it creates an extra expense for any transfer due to having to go through an FFL is my reason for being opposed to this. I already do a bill of sale for any gun coming into or out of my collection, a quick phone call while the buyer looks over his purchase wouldn't hurt me.
Would you be able to point to any evidence that background checks have reduced gun crimes?
