That's not being safe, that's being legal and abiding by the laws we have in place.
I think you missed my point.
It's illegal to sell a firearm to someone from another state, without going through an FFL.
Shouldn't it be equally as illegal to purchase a firearm from someone from another state without going through an FFL as well?
It's not illegal fo a felon to purchase a firearm, but it illegal to sell a firearm to a felon or for a felon to be in possession of a firearm.
This isn't completely accurate, it is illegal to KNOWINGLY sell a firearm to felon or other prohibited person, or to KNOWINGLY sell to a resident of aother state.
The key word is knowingly.
There isn't any law that requires you to investigate the home resident state or the legal status of a buyer in a private firearm transaction.
As a side note there is a long list of reasons a person maybe a prohibited person, (felon, domestic violence conviction, currently under indictment, in the country illegally, adjudicated mentally ill, dishonorable discharge from the armed service, the illegal use of controled substances, etc).
That idea that having one show a state ID and or a WCL by no means proves that the buyer isn't a prohibited person, it just gives the seller a false sense of security...
