Ever wonder how criminals are able to get guns so easily? It’s depressingly simple. On any given weekend, at dozens of gun shows held in states across the country — criminals can buy guns from “private sellers” who are not required to perform background checks…

Today, New York City is releasing the results of a multi-state investigation into this activity: “Gun Show Undercover.” We sent investigators with hidden cameras to seven gun shows across Ohio, Tennessee and Nevada, and we found out just how easy it is for criminals and the mentally ill to walk in and buy guns — no questions asked…

Our investigators told the private sellers that they “probably couldn’t pass a background check” — and at that point, the seller should have sent them away. Because even private sellers are prohibited by federal law from selling to those who they have reason to suspect could not pass a background check.

Instead, 19 out of 30 private sellers made the sale.
