I'm not sure I'd trust our Police not to get physical if rule by government was needed.
I think most would have to comply or be imprisoned like in Italy
People aren't being imprisoned in italy stop reading the headlines read the articles.
You do realise that in Italy people.are still going to work,public transport is still running, shops still open, bars and restaurants still open, the lockdown is more about stopping people leaving regions.
Most people dieing in in Italy have underlying health conditions and aged on average 80 which isn't good, but hardly surprising.
