When I was a grad student I contacted a journal to tell them my PI had falsified their data. The journal never responded. I also contacted my university's legal department. They invited me in for an hour, said they would talk to me again soon, and never spoke to me or responded to my calls again after that. This was in a Top-10-in-the-USA CS program. I have close to zero trust in academia. This is why we have a "reproducibility crisis".
