Call the cops and keep yourself safe.

Unless he is discriminating against you because of your race, sex, age, etc it is perfectly legal.

You can get your medical records and take them to a malpractice attorney for an evaluation. Best of luck.

As long as he was on his own property it is perfectly legal.

The cop was not required to read you your Miranda rights. That is a common myth. You need to retain an attorney and present them this info.

This is a Q&A site. You have not asked a question, but rather made a statement.

I agree. Sounds like a personnel matter, not a legal matter.

If your potential employer asks for it, yes.

That is up to a judge to decide. You need to retain a local attorney.

While we don't know how they got your info you can simply ignore it and not be a part of the lawsuit.
