what to do?

[Vincent]

Hardly a gun show goes by here without some kind of contraband showing up. Undocumented machine guns are the most common. Drop in auto-sears, suppressors, live grenades…. you name it. One guy had a nice StG 44. Another had a mint M14. And not one of these folks wanted to believe they had something illegal. When I told them they would nod and say other dealers told them the same thing. Then they went to the next table and tried to sell it.
