What's throw me off of the 'the Cia did it' is that the authors left clues, and the operation wasn't that tight.

It was tight enough, sure. BTW that's way there is no way Russia did it, their opsec is shit and they get caught by osint all the time. But not as clean as what some alleged Cia operations are (like what happened to French assets in Libya, Clinton's e-mail hinted it was an op, yet without the leak nobody's would even think USA was involved). This was sloppier imho.

It still can be US work, but I would be surprised if it were a federal agency.
