I believe you are correct on all counts except for the sniper bit. He was shot execution style by pistol, and the police have a sound locationsystem for gun shots , which had registered on their system. When they got there about 15 minutes after the fact, Lieutenant Quarles Harris Jr. was dead, executed gangland style, with no witnesses present. It is my understnading thet Harris was executed in his car.
It looked like a drug purchase gone bad, and maybe Harris was a user, only the person he thought was his pusher, was not. He was capped on the spot.
Oh, you’re right about it not being a sniper and the gun shot locator. I remember, now. I thought that he was supposed to be meeting the FBI contact and was early, so he was sitting in his car, but that could have been speculation at the time.
I like the drug purchase theory. Even if he was meeting with the FBI that day, he could have had a purchase scheduled.
I have to wonder if the toxicology report showed a history of drug use.
You know, the more I think about it, the story about drug use is a little too convenient, as well. Brennan could claim that Harris was working for someone else, not him, when he accessed the files, someone who blackmailing over his drug use.
At any rate, Brennan should have been held responsible for the breaching of the passport files.
