Yeah, the thing that's missing in the commentary is that Turnbull used it as a throwaway line. He doesn't actually think you can break mathematical laws. He's not a stupid man, and was just answering a comment comparing natural laws against national laws, which are clearly not the same thing.

One thing I miss from yesteryear is how people used to be able to understand what a politician was saying between the lines, and when a politician was going for a bit of dry humour. Now they just analyse the surface content. It's pretty sad.
