Re: Policing by consent
@Hague - The point is that you're supposed to stay at home.
The provision to "do exercise" means you can leave your home for a walk/run/bike, for health and all that. It doesn't mean "go for a walk" a la the middle classes, where you drive to the Walking Place and go for a stroll.
Either you're getting essentials or going to work. Other than that, stay home, go outside in a private area if you have one, so the poor buggers who don't can use the nearby public areas.
I'm a climber. It's perfect climbing weather. I could get into my local gym for a sneaky climb. But I don't go and do it, because STAY THE FUCK AT HOME.
