Im only thinking of the original owner.Because as safes are property, they are regularly sold. This is why a serial number is used...
If the feds know its a liberty, then they could still get the backdoor code from liberty without a serial number.
If you remove the number, it lowers the resell value. If you buy one used, then removing the serial number should work...
the answer to both of them is "I don't know because it's not happening to me right now." Plus the 'pay to keep' is pretty non specific. Pay the full retail or pay $10.00 for a lifetime ID card that boot scoots me past the BGC and GCA silliness?
