I have been asked to write an affidavit for an assult case. I did not witness the assult but the person being charge assulted me (I did not press charges) as well as harass me online via IM and PM on a local forum as well as phone calls. The only "proof" that I have is print outs of the PM's. Quite frankly I do not want to be involved in this situation for fear of it coming back on me...the guy has left me alone. I guess what my question is, I have no clue what I am doing, what is the best way to go about writing this affidavit?

Any help would be greatly appreciated.
