My question involves defamation in the state of: California.
I have a classmate who became upset with me because a classmate & I had to report her to a professor for being uncooperative on a group assignment. Since that date she has taken my cell phone & threw it in the dirty tampon bin (in the bathroom) and filed a false report against me with our school saying that I told her I would "shoot her if she embarrassed me" this is something I would never say & apparently the school agreed & told her that if she was so "afraid" of me (as she had claimed to be) then it shouldn't have taken her 2 moths to report this. She then decided to take it one step further & tried to file a report with the Police Dept. who in fact said the same thing, they were not even going to investigate it because it's not legit.
I am concerned she will attempt to take this further & was thinking I should have a cease & desist served on her because from what I know the burden of proof is on her & since she can not prove this happened she is committing slander & libel by continuing to push the issue.
What should I do? I'm worried she will damage my reputation both at school and in the field.
