My worry is how much of this Act will be repealed when this is all over. Post 9/11 the Bush Administration brought in Draconian measures to monitor people which are still in place. Very worrying....The Coronavirus bill that is going through Parliament has provision to force the closure of airports to passengers for the safety of the population, if a risk has been identified. Schedule 19 of the bill refers to Border Force being able to sufficiently provide cover at any relevant port, interpretation of this being any port of entry requiring the presence of immigration and/or customs, land, sea or air, may be closed.
Things continue as is, nothing but cargo will be able to move. I expect amendments to include closure of motorways to private vehicles. This is wartime style management of crises, new territory for most of us.
....but I have a theory and I have started to write a book. Just need some characters, a story line and setting...
