I don't think you need a lawyer, there's a statutory process for you to make anonymous complaints for violations to the principal, and if necessary appeal to the Education Department. (Take a look at Cal. Education Code 49013.). Seems like you could probably do that without a lawyer.
That has been done, with no effect. Being completely sincere, I would be happy to have the name of a law firm that would handle these cases. It comes up all the time with parents I know.
