My crystal balls sees you being sued and possibly criminally charged.

Absent serious medical injuries, there is no case. And, no way to prove that the fingernail was actually in your food when you ordered it.

In addition to the above, your son can retain private counsel in lieu of his PD.

Of course you can. Your youth is not a defense.........

Hearsay is a term reserved for court rooms. The short answer to your question is yes.

They don't have to tell you. It is their platform. They decide who uses it. Just like WalMart decides who can go into their store.

Sure you can. The cost of hiring a lawyer will be about 10K. You are entitled to 40 minutes worth of inconvenience. Basically nothing.

Forced you how? Unless you can prove that he threatened you with death or great bodily harm, your lawsuit is going nowhere. He will simply say you...

You would file suit in the Court of Claims, assuming you have already applied to the ABCMR.

IMO, this is unlikely. By the time they allow you the time conform to the requirements, you will be retirement eligible.
