What can I do when I reported bullying behavior and in turn was blamed for it?

Question Details: I reported 2 instances of bullying from a co-worker with a history of this behavior at previous employers. The first incident had multiple witnesses and the bully received a verbal warning; I received nothing at all. The second incident lasted more than 5 minutes, however the 1 co-worker who would have witnessed it said that he had headphones on so couldn't serve as a witness as he didn't hear anything. I legally captured just over 3 minutes of the incident on an audio recording. The bully never denied it, only that he didn't know why his anger was out of control. The company did a sham investigation in which the attorney they hired to investigate produced a report full of references to a conversation that we didn't have and said the bully did nothing wrong. I don't think he ever reviewed the audio. The EAP (Employee Assistance Program) counselor told me that our EAP called him and directed him to investigate me for things that were not relevant to the situation. His words were, "I believe someone at your company is protecting him". HR was not happy that I had reported their star performer and constantly tried to persuade me into agreeing that I overreacted and that this person was under a lot of stress, etc. Now, 3 months later, I'm receiving a write-up for both instances. On top of the write-up, my boss is fabricating issues on my performance review and I know it's for nothing more than to show a false paper trail to justify firing me for something other than the bullying instances. What should I be doing in order to protect myself? Can I bring legal action against them? I am very distraught over this matter and losing my job isn't really an option?
