There were a number of craven souls that did line up in the last few days of December to register their arms and magazines, but that is not the reason that Connecticut’s government is spurred to call for amnesty. They’re calling for an amnesty period because their internal estimates likely show that their attempt to browbeat the citizenry into registering their arms for future confiscation has been a abject failure, and they are desperate to do anything they can do to encourage compliance now that their threats have failed.
Of course, these unconstitutional tyrants would never, ever think of backing down and repealing the law. Law is eternal. When they want it to be.
