Why doesn't FTL quantum tunneling violate causality?

It seems that a bunch of experiments confirmed that particles tunnel through barriers faster than what would be expected if they were traveling normally at the speed of light. I’m referring to a study specifically by the Keller group in 2008 but this seems to be the consensus today (according to Wikipedia at least). 

I'm not ready to believe that relativity would fail so quickly and I'm inclined to think that even if FTL tunneling is possible, it wouldn't allow FTL communication. But I fail to see how that's the case.

edit: corrected group name to 'Keller group'

It can't communicate information. Stuff can travel faster than c- like how the Universe has expanded faster than the speed of light- but information cannot be transferred faster than c. Quantum tunneling is random- you can't *make* a particle jump a light year away instantly- so it can't transfer information.
