What? I mentioned a third party investigation and you're saying they "investigated themselves" and brought up law firms for some reason. While completely ignoring the fact there is no evidence outside of the claims made by the ex employee

What else can you do in that situation? Fire other employees based on hearsay? Unfortunately, you have no idea what you're talking about about. It's perfectly fine to dislike a companies actions but let's not perpetuate falsehoods and look like clowns.
