The lefties were so upset when ACORN was “set up” in an undercover sting but think it’s just aces when gun show vendors are “set up.”
Unless the purchaser is truly a felon then no crime was commited. A buyer who says he “might” not be able to pass a background check does not mean that the sale can’t legally go through. Most people don’t know what does and does not disqualify a person from firearms ownership.
I miss the olden days when FFL’s were prohibited from selling at gun shows. The shows were all people who loved guns and wanted to sell/trade among themselves. Now they’re largely just extensions of storefront showrooms and prices are much higher.
