In the case of the cop killer in Tarpon Springs, Florida today, the perp, with 30 arrests, bought his gun from “some guy” in Tampa. I’m sure “the guy” handled all the proper paperwork efficiently. /s
“out of car no doubt”
If it was a private sale, then there’s no background check. Are you saying that you think there should be checks on private sales as well? Considering Margo Bronstein and the huge numbers of people whom are killed in car accidents annually, maybe there should be no more private sales of cars between individuals without expensive and intrusive Federal background checks.
