Because paint ball guns spark the thought "splotch or paint", they are seldom considered in the same category as firearms.
I want part of that fixed.
I want a paintball gun being handled inside or on a moving vehicle, or in a public place, to be considered the same as brandishing a loaded pistol, rifle, or shotgun.
Many paintball guns can be cranked up to cause injury to unprotected body parts, especially the face. And, unlike the guns Mexican drug cartels are buying - contrary to supposedly trustworthy sources (US Secretary of State Hilary Rodham Clinton, US President Barack Hussein Obama, the President of Mexico), paintball guns can fire in automatic mode.
The paintball goo might be machine washable. That doesn't do much for buildings that don't fit in washers. Or for broken glass, startled and scared drivers, etc. Or the obscured vision of paint-splotched windshields or car windows in the midst of traffic.
The paintball gun, used in public, has as great a chance of causing property harm and injury as a firearm. And brandishing a paintball gun, or drive-by shootings with a paintball gun, should be handled as if the gun were a gunpowder-propelled firearm.
Unlike a pistol, a paintball gun cannot be considered a prospect for personal defense - meaning there is less reason to have one in public than a loaded gun.
