For that to happen a dictatorship would have to be established with full control of the armed forces. Which would mean a civil war before authorities start going door to door. In the current state of affairs, as big a socialist as Obama and his cohorts are, the authorities will not be going door to door.
I would like to provide some food for thought on the question of our police & military forces transformed into enforcers of the will of the State:
It is said that both the Gestapo and the East German Stasi relied on informers at the ratio of one secret police agent to every five informants. The difference was that under Nazi rule the snitches were nearly all volunteers enamored of Hitlerism, while under Communist rule the informants were unwilling but compromised citizens, informing on their neighbors in order to save their own hides.
Government snitch hotlines have been used in the U.S. previously and are likely to be used again in states like New York & Connecticut. “Call this number to report an illegal gun, and you don’t have to give your name!”
If a full blown confiscation campaign ever eventuates, the govags will encourage neighbor to spy on neighbor, both to facilitate rounding up guns, and to divide & conquer the populace (in the Third Reich it was called `the atomization of society’).
Either the snitch lines will be spammed to death (if people act to resist) or neighbors with grudges will use them for revenge.
Another perspective: in the Soviet Union under Stalin, the NKVD attempted to use “anonimkii”, which was to denounce suspected opponents of the regime, using letters mailed to police headquarters with no return address or even signature. This quickly spun out of control with thousands of anonimkii & thousands of false arrests until the NKVD ended the practice & returned to using known informants to smoke out dissidents.
Govags already know they don’t have the numbers to kick in every door in America; they will resort to force multipliers such as I have noted above.
Thoughts, anyone?
