There is some... interesting evidence pointing that way, e.g. how the coup was done when Erdogan was nowhere to be found and safe. As far as I can tell, it was either orchestrated by him, or the organizers were supremely incompetent in even the most basic details (who starts a coup without knowing where the damn target is?).
It would not be the first coup to fail because of bad timing. It is likely that, if it was a not a government organised shenanigan, the organizers panicked and enforced their plans too early making a mess of the timing and available data.
On the other hand, considering the effectiveness of the government dealing with it and speed of how everything happened after the coup was struck down (and yes, I'm biased due to lack of proper reporting like everyone everywhere) it sure smells like a well orchestrated coup, only not from the people who are currently being prosecuted but from those prosecuting.
I'm going to do a Godwin here and get Martinus van der Lubbe involved. You can figure out the rest.
