I mean, at most employers you literally can't publicly share any material produced on a work computer or context, unless you feel like being sued (for violating a non-disclosure agreement). When it comes to law-violating stuff, of course in that case the NDA won't apply to sharing stuff with law enforcement etc. .. but that doesn't mean the stuff can be shared publicly (unless it becomes part of a public court case of course). It's not all that easy to blow the whistle on something and "provide receipts" to the general public (unless you don't mind having lawsuits filed against you I guess). This is why you generally give such people the benefit of the doubt -- they basically have no other option but to make their case as fairly and reasonably as they can, while still protecting themselves to at least some basic degree. If it really came to it, the claims _can_ be verified, for example in a court case, where the process of discovery would reveal all the HR records and whatever else.
