Just read the whole piece (of crap). He proposes a mandatory buyback like Australia did. $500 per gun. Estimates that they could collect 20-25% of the guns in America, somewhere around 60,000,000 guns. So, at $500 per gun, that's $30,000,000,000. Where in the hell is the US government going to come up with $30 Billion for this? And, there's that pesky 2A issue.
I've said before, and I'll write it here again. The only way full confiscation would work is if 2A was repealed (or SCOTUS ruled it was a collective right, not individual). Then the court would have to suspend 4A (search and seizure and warrant), and maybe 5A (self incrimination), and conduct a house by house sweep of the country. Not enough cops for that, so posse comitatus gets suspended, and they press the military into service. Got to deploy these troops in CONUS, so maybe 3A gets suspended. Now, how long will everyone go along with all of this? Yeah, the leftists may be on board with searching for guns, but what happens when they start searching every house? And find that little stash of weed/coke? Or the illegal cable hook-up? And that becomes admissible because 4A was suspended. And then, imagine how this would actually work. Start at one coast, sweep to the other? This is a big damn country, with acres and acres of hiding places. Don't even need to hide them for long...just a couple of weeks until the sweep passes by...
Like I said, it can't work unless we let it work. Not bloody likely.
