matt bracken tells you some of what's coming;

There is currently a lot of attention being paid to new Democrat-proposed gun control laws, particularly House Bill 127, which would require national registration and licensing of all firearms, would ban broad categories of semi-automatic weapons, ban most ammunition magazines, and so on. One of the most frequent replies to these proposed laws is that there are not enough local or federal SWAT Team door-kickers to go house to house on gun confiscation raids, and if they tried, they would 1. soon run out of door-kickers and 2. instigate Civil War Two.

But in the modern digital era, I believe that Team Tyranny won’t have to do much door-to-door gun confiscation. I think that a few show-piece gun confiscation raids using overwhelming force at 4AM (that are designed for network TV audiences) will be sufficient. Instead, they’ll just send citizens a notice by text, email and registered snail-mail that they already know what newly-illegal guns they possess. This list will be based on AI programs scraping and data-mining your social media history, credit card purchases, and all past FFL sales records, which surely will be collected as part of the new law.

All of this information will be knitted together much the way that the IRS does business. I borrowed this paradigm from “Old Curmudgeon” on a Free Republic thread:
“Have you noticed how the IRS manages to enforce the tax laws? Every taxable transaction is documented by multiple parties so that one party’s failure to report will be revealed by the another party’s paperwork. Then the person who violated the tax law is made an example of, a horrible example, causing reasonable people to be very afraid of the IRS. They will use a similar method to end gun ownership.”

And don’t think for a minute that they won’t get all the gun sales records, once they pass their “Emergency Measures To Prevent Domestic Terrorism Act.”............read more........
