I assume that it looked like Garmashov was part of the malfeasance, that on the face of it he signed off the improperly trained/rated TI who died with his student at Lodi. So the USPA came down hard on him, pulling ratings. Before he had any chance to defend himself. Without following proper procedure. Only LATER did it become understood that the signature must have been forged. (Luckily Garmashov had a good alibi, that he was out of the country at the time.) There's no evidence presented about that but hopefully that has been established as a true fact.
I wonder what the timeline is. The Lodi fatality was August 2016 and now it is 2023. How long did it take to start finding out about the whole system of forgeries and bad TI certification? And that Garmashov's signature was forged? Could the USPA have headed off this whole mess by a quick turnaround, "We thought we were doing the right thing but we didn't follow all our procedures and were deceived by Robert Pooley; we're sorry to Mr. Garmashov who is again a member in good standing"?
I wonder what UPT did when it came to tandem ratings. Did they follow USPA's lead? Or do something entirely different?
For reference, the original tandem fatality thread https://www.dropzone.com/forums/topic/26768-fatality-x2---lodi,-ca---7-august-2016/ (I haven't gone through it all!)
Pooley's arrest in 2021 (short thread with no followup): https://www.dropzone.com/forums/topic/272535-instructor-arrestedwas-lodi-tandem-fatality/
The galling thing is that the USPA covered it up (rather than apologizing publicly), and in mediation still wanted to prevent Garmashov from ever being a USPA member (figuratively saying "you may be right but we still think you're an asshole for fighting us, you'll never work in this town again, that is, you'll never hold a USPA rating again").
EDIT:
One does find some stuff when searching for Rob Pooley on DZ.
For example, a copy of the announcement by USPA at about the start of Sept 2016 that some of Dause, Pooley and Germashov's ratings had been pulled: https://www.dropzone.com/forums/topic/87-so-you-think-you're-a-ti%3F--are-you-sure%3F/?do=findComment&comment=4520528 Plus the whole TI investigation ("About 120 must undergo a new USPA-developed refresher course (some immediately and most by September 30), while some 20 others have had their ratings suspended and must undergo a full and complete tandem instructor rating course ")
