I really don’t care; they should have known the truth. And if they didn’t, they should have informed us on that, too.
The whole issue to me is that they acted like the authoritative figure who you could trust. Turns out, we could not. So why should I trust them from now on? They damaged it, and didn’t try to “fix” it. They just called everyone that asked questions conspiracy theorists, combining everyone into one word “wappie”. The officials did. They actually used that word multiple times on TV.
So I don’t know if they knew, but it’s besides the point.
