> If someone makes a false claim that results in personal expenses for me that sounds like libel or defamation. Then you don't know what libel or defamation is. But, yes, if someone makes a false report against you and that results in injuries to your reputation you can totally sue them for slander, libel or defamation (depending on how the report was filed). As far as I know, no laws hide the identity of people reporting crimes. However, for very good reasons, we allow people to report crimes anonymously.
