I think they said the same thing in the UK Canada and Australia.
You're comparing us to two countries that have 20%, 12%, and 8% (respectively) of the population of the USA (where we have WAY more guns that people)??? They have no enumerated Right to Keep and Bear Arms (or any other rights, for that matter) and VERY few guns relative to the population. That's not to also mention the nature of those cultures, which are well-known to be passive and compliant.
Again.... here we have 343 million people with probably close to a billion guns (far more than the oft-reported 400 million). And we have about 720,000 police officers. There are approximately 142 million households in the USA. Gallup reports that 44% of homes have guns. I think that's likely low and perhaps way low.
Let's have some fun with numbers!
So, 142 million homes. Let's say that only 50% actually own guns. That comes to 71 million households with guns. Many of them with more than one gun.
Let's also assume that the gun confiscation squads would have (at LEAST) 10 officers per squad. They're not going to send a lone officer, or even 2 or 3 officers, to a home to confiscate weapons, eh? It's potentially a dangerous operation, so they'll need overwhelming numbers and force to be on the safe side. And let's assume they could execute 6 confiscation visits per day (optimistic).
720,000 officers would make 72,000 squads, theoretically. Of course, this is making the impossible assumption that 100% (ALL) the officers would be on this mission and not conducting their normal daily law enforcement functions. So, let's then assume that they could allocate a GENEROUS 20% of the officers to this confiscation duty. Let's amend that to 14,400 confiscation squads.
So 14,400 squads X 6 raids per day = 86,400 raids per day.
74 million households divided by 86,400 raids per day = 856 days (2.35 years assuming 7 days / week) of confiscations to get to everyone.
Word would spread in just the first few days, and I'd expect a "pandemic" of "tragic boating accidents."
And I dare suggest that is a VERY "optimistic" set of calculations. I also dare suggest that there would be SIGNIFICANT shall we say "attrition" of those confiscation squads... 'cuz gun-owning Americans would be so cooperative! NOT! It will NOT be a "cake walk" in the American landscape.
Even assuming the improbable decimation of the Constitution....
It is a logistical impossibility to execute a nationwide confiscation.
That's my story, and I'm stickin' to it!
