1. Never said I knew that his death wasn't related. I did say that it didn't look like a professional hit....Rich was shot in the back and was still alive when the police got there.
2. Could it possibly have been some other individual who either feared that Rich knew too much or someone who was looking to mislead investigators? Sure.
3. Is there any evidence that someone had physical access to the email server to use a thumbdrive to steal the entire email data file? Are you kidding? The current technology is against the idea that someone simply pulled the DAT file. More like they had a way to scout through looking for email to or from specific people. There are utilities that exist to let you do that....which means that the software on the email server would be a clue.
4. I have not read that IP addresses found in the email server log pointed at Moscow. More likely they pointed to intermediate machines....so there was a trail that ended up
in a system or in systems that the investigators had tracked and knew belonged to GRU or other groups.
5. I think you give the Russians too much credit. Some murders traced to them have been fairly clumsy...including the injection of a small metal ball filled with poison...

6. The idea that it was a botched mugging is not all that implausible. Rich appeared to have fought with his attacker. His knuckles were bruised and he was shot in the back...making me think there were either two attackers or that he was knocked down and shot on the ground...From police accounts the responding police officers were on scene within a couple of minutes. If the mugger was simply looking for a score and the shooting was not planned....the nearly instantaneous sound of a nearby police siren would be a good reason to run.
5. The bullshit about Seth Rich being murdered in the hospital and it being covered up by the police and attending doctors and nurses is just too over the top.
I'm always amazed at just how outlandish the conspiracy theories get. The idea that a botched murder is then somehow reported to the top dog and then all of the necessary top police, hospital employees and doctors are contacted, paid off and the murder in the OR is organized is too nuts.
