The long gun registry would have failed even if it had been delivered on time and under budget, to spec. They had less than 10% compliance with the law and putting 5-10% of the population in jail was never going to happen. Much like Prohibition in the states banning things that large portions of the population have no problem with doesn’t work, and the Canadian populace is plugged in to the US media enough to know that a gun registry is a prerequisite for any campaign of confiscation.
