re: Taking our Guns.....how do they do it?

Door to door gun confiscation is literally impossible.

It would literally require a full search of every domicile and property in the US.

Imagine the time and manpower it takes to do a complete search of one house/property in the service of a warrant related to a crime.

Now, imagine doing that to every residential property in the country.

There are roughly 120,000,000 residential houses/units in the U.S.

Then consider people hiding/burying weapons once confiscation began.

Not happening.
