"they" did make it known that the Skripals had moved to NZ but that has to be bollocks. They are so worried about being targetted they can't testify, even remotely, but their location gets widely publicised? Nah.

I'm not convinced they are still alive and it's telling they haven't even tried to manufacture any kind of media appearance from them. It would be like The Dead Parrot sketch: There! He moved! You kicked the cage!

Their silence, permanent or otherwise, definitely speaks volumes.
