The report concluded there was no evidence that Tessier-Lavigne himself manipulated data in the papers reviewed, nor that he knew about manipulation at the time.
What kind of absolute horse shit is this? He is the PRINCIPAL AUTHOR on these papers. That means it's his data. He's not co-author, now a peer reviewer, not an advisor. It is absolutely insane that he wrote these papers and didn't validate or review the data hundreds of times before putting it in publication. This is some golden parachute shit.
