Sorry Dave, until you know the "details", or until you know if it is "safe"? Isn't that the crux of the matter here and, in fact, the question being asked? We all have levels of "safeness" that we accept.

In other words, the issue here is that businesses are going to go bust, peoples livelihoods lost, because, in the rush, the scientists advising the government, or the ministers in government, have simply not factored in that it is a hell of a lot easier to spread people around a stadium, at reduced capacity, than it is to spread them around a restaurant, or a bus...
