And what do you propose they do? Have police / army in the streets rounding people up?
The police and army are on the streets in my MIL's country in Europe, yes, they issue fines, have a word with people out for no reason, everyone is on lockdown and that's that! Allowed out for food shopping and to go to work and you have to prove with evidence that's where you are going. This is not Italy by the way.
