I was a firearms dealer in the 90's, I want to make a point for you to think on. How come with the gun violence in the major cities, we're not getting a finger print from ANY shell casings, a traced gun back to the original gun owners or shops, no prosecution to anyone for straw purchases, Nothing! EVERY gun that comes out of plant is serial numbered and a manifest is kept where EVERY gun goes, the ATF has this, yet you hear nothing of any arrests. Can you explain why?
