Meanwhile, it Connecticut,

Other officials think the low registration numbers are due to ignorance on behalf of gun owners who aren’t aware of the new law.
Maybe a few; the others are sending you a message: "We won't do it.  So come put thousands of people in jail because you made our firearms illegal."

Police had received 47,916 applications for “assault weapons certificates” and 21,000 incomplete applications as of Dec. 31, Lt. Paul Vance told The Courant.
Hmmm, almost half as many incomplete as complete; wonder how many of those are part of the message?
Mike Lawlor, “the state’s top official in criminal justice,” suggested maybe the firearms unit in Connecticut could “sent them a letter.” However, he said an aggressive push to prosecute gun owners in the state is not going to happen at this point.
Translation: "My Karl Marx, how much trouble happens if we try to start arresting all these people!"  Probably fed by the cops saying "Do you have any idea what you're going to look like if you tell us to start throwing people in jail for having the same guns they've owned for years?  And we're really not happy about winding up being labeled the Connecticut Stasi; we have to work around all these people and their friends and family."

Don't make a  mistake, I don't doubt there are plenty of badge carriers who'd go out and start kicking doors long as they have an order to cover them; but some won't, and some on the line are considering being told "We don't serve your kind" at the cafe and such.
