Well you are talking about national legislation I suspect. There are states whose gun laws comply with your dictum, and at the federal level there is accomodation for compassionate release and rational release (as in your example). Many state have also adopted these policies and procedures. Fining airlines is perhaps a federal matter since the do control air transport in this country.
At this point I have zero recommendations. Certainly we can’t legislate that people are nice to each other or don’t call names.
