Was Mata Hari guilty?

[Cainkane1]

I've read that she was railroaded and wrongly convicted. I've also read that she would have been found innocent like Dreyfus if she had had a benefactor like he did.

I'd heard that she was a very small fish that was used as a large scapegoat.

Note for clarity: a small, but still guilty, fish.
