How do they know who has a rifle?
Apparently they’ve been getting the info from the NICS forms at gun stores? Yes, I know, they’re strictly forbidden from doing that, but what the heck?
In this case, I think the notices are going out to people who stupidly registered, but after the deadline.
Someone named Holder ordered a SQL query on NCIS for CT background checks? That would be possible but not foolproof, and certainly miss any illegal purchases.
When you buy a firearm and the gun dealer calls in for a check - it only goes down as either a "long gun", "hand gun",or "other".
Only the gun dealer has a record of model and serial number.
They would have to physically check the records of all gun dealers to find out who's bought rifles in the now-banned categories.
BUT,
Up until this year, you could sell, trade, or give away any type of long gun without filing ANY type of paperwork.
SO,
They still have no idea who has what, even after they (illegally) check the gun store records.
Almost certainly every person who allegedly didn't register is because they no longer own a scarey-looking rifle........
