Why does everyone believe that we’ll be waiting at the door if they start confiscation?
They will use trickery at first. They know that a full on door-to-door will not work.
Maybe send threatening letters to all gun owners.
We know you have such and such gun and you will be fined $10 per day until you turn it in or show proof that it was lost/stolen.
After 30 days they will suspend your drivers license.
After 60 days a warrant for your arrest will be issued.
After 90 days you are now considered a threat to society and armed and dangerous.
