You can't just start leaking internal documents and making accusations without evidence. ...that will get you fired, and possibly in jail.
You need to talk to a lawyer, follow the legal process, and make allegations that you can PROVE.
So many whistle-blowers come out with wild stories (often true), but since they bring zero evidence to the table they are ignored. ...and if they have evidence, they just blindly leak it to the press without going through the process, which can endanger people/privacy and destroy IP.
Don't get me wrong - whistleblowers are important, but if you really want to make positive change and not just stick it to your employer - do it responsibly.
