A lot of places used "shelter-in-place", and officially over here it's still "stay-at-home". The colloquial term having switched so totally to "lockdown" is another symptom of people caring for it less and less.
I was endlessly annoyed by the misuse of the term "shetler-in-place" by so many state and local governments. At no point should anyone, anywhere have sheltered in place due to this pandemic, which is an established term in emergency management where people are instructed to shelter in whatever structure they happen to be located at the time of the emergency.
What happened last spring was more or less incarceration. We weren't free. We weren't allowed to leave our houses. The term "lockdown" works quite well.
Thankfully, while there were a few places that attempted to restrict outings to "essential" trips, it never was enforceable. I am not a fan of many things police do, but I am proud that my local sheriff announced that he would not enforce any such order.
Free societies don’t have lockdowns. Prisons do. One would think that the government would come up with a better term, if only out of self interest.
But then perhaps that’s the point.
