Yes lock us down, bring the military and police in to enforce it.
I do think we need to isolate. It will save lives. I am very worried about the speed a democratic country goes from freedom to 'lock us in our houses without a crime or trial and enforce it with the military'. Allowing and in fact rushing towards martial law? Letting parliament speed legislation through without scrutiny?
Once they done it once for a good reason it's a lot easier to do it for a bad one.
