Lets say you're a college student with a passion for amateur chemistry. Your going to school to be a chemist. As such, you make legal purchases online for equipment over several years. At some point, the government finds your purchases suspicious. Federal agents come over to your home to investigate. During their interview, its mentioned that they would like to search your home. You object and they threaten to tell the university and your work place that you are a "person of interest" in a criminal investigation.
If they were to follow through with their threat and you suffer damages in the form of getting kicked out of school and/or losing your job. Is it possible to sue the government? How would this be done?
