A lawyer would be if you were harmed
A lawyer can also help guide you through the legal and procedural issues. Lawyers are not for just if you are harmed.
It would probably also help you a bit more with legitimacy, if you can get a known lawyer helping you… Cause any crank can make a claim, but a known lawyer wont risk their reputation/license/job on happenstance with little evidence.
Pointless.
You’d need 500 signed affidavits to be taken seriously. Anyone can just forge a signature. Affidavits are signed under oath, under penalty of law.
