a point to consider, indy
a seller working a gun show can't sell a firearm without a back ground check
private citizens can sell a firearm to whoever they want without a back ground check whether they meet at home, a gas station, a bookstore. they can even do it at a gun show in the parking lot, if they hide it from the people putting on the event, who will ask them not to do it and probably make them leave the premises if they persist, just to avoid legal hassles.
ergo, there is really no such thing as a "gunshow loophole" to close. them there's weasel words
what you really want is to ban private sales of firearms without a background check
does that make sense?
