Canada is about to get an “evergreen” gun ban. “Evergreening” is a term from the software industry. It refers to automatic updates that occur in the background, like when your smartphone’s operating system upgrades itself in the middle of the night while you’re in la-la land. That might be convenient for computer technology. But when you’re talking about changes to a law that affects hundreds of thousands of Canadians, it’s undemocratic to say the least. But with the “evergreen” ban promised this week by Public Safety Minister Bill Blair, it’s possible to go to bed a fully law-abiding citizen and wake up in possession of illegal firearms.
