The point is the Government are enacting policies the opposition thought might be a good idea and might well be inevitable a few days later but they are now criticising the government for doing the what they called for a few days earlier.
Sigh. The point is BJ has made the decision now that he should have made several days ago - and people made their plans on what he said then.
A moot point, however, is that anyone with a bit of a brain should have limited their planned mixing/contact anyway, not waited for anyone (especially BJ) to tell them what to do. This was always likely to happen.
