I'd certainly support complete registration of all firearms as a decent
start. Used firearms must be registered, too. Along with the
registration, a mandatory background check of the purchaser. All
firearms, no exceptions.
I guess it doesn't bother me to do this since all my guns are already
registered to me in a data base that the state keeps. It's not a bother
or hassle in any way and doesn't restrict my ability to have and use them.
If I sell one an easy to file (on-line from home) report of the
transaction is sent to the state with the gun serial number, my permit
number and the new owner's permit number. Takes all of 5 minutes to do.
If lost or stolen a similar report is made to the state. No big deal.
It is all just meaningless bureaucracy tho. We have not had a "who
done it" mass shooting since the DC sniper and they still had the gun
at the same time they had the shooter.
