I would not necessarily say that is was the drills.
I think the more important thing here is that we came at it by asking what sort of legal framework we could use to help the population to go through a difficult time together. I think they worked with some of this individual liberty versus the collective group of lives at stake, and then it's question of whether they can handle that kind of balance.
This was the very important legal framework that Korea was able to handle, when the Korean people went through SARS and then the MERS crisis in the past.
