I think if there'd been more enforcement in public areas months ago, people would understand that it's important to stay as safe as possible. Obviously there won't be any enforcement in people's houses (unless they're clearly having a loud and packed party), so once again it depends on whether folk are self-disciplined or not.
Enforcement of what and where though? In public areas, predominantly outside, the science is saying that covid is less of a risk compared to indoors.
Doesn't have to be that strict. A valid solution would be to stop people travelling through different regions (unless there was a valid reason like work, medical needs etc.), which is what they are currently doing in Italy. Put police on borders of regions, and that way you're going to stop the spread from different tiered areas, which is the main method of the virus spread at the moment.
A nice idea, but in reality it's completely not feasible given the current resources of the police force.
