The problem with taking “proportionate” as a criterion, is that you need to be “proportionate” to a state of affairs that will only be visible after 14 days (by the number of ambulances) or appr 5 days (if you are testing well). This has signified a constant struggle to identify “proportionate” by leaders, with a tendency (in my view) to err on the side of too much liberty of movements and too late restrictions of it.
