>How does this case differ from Snowden's situation?

One case is an individual whistleblowing (at the very least in his mind) against his own government, and he is now on the run.

The other case is a foreign government operating agents performing activity that is illegal in that country and throughout the world.

Seem very different to me.

The closet parallel I can think of is the Rainbow Warrior bombing/murder case in New Zealand, where French agents performed the bombing. The result was detention of the spies, some diplomatic shenanigans and eventually a negotiated/arbitrated solution that even involved visa-free access for New Zealanders to France.
