Cops are not required to read you your rights. That is a myth from too much Law and Order TV shows.

Not without some form of injury. Otherwise, people would drop things in their food and sue for it.

The cops don't witness most crimes they cite people for.

Ask your parents. Not if you were my kid. I would call the cops in a heartbeat and have him arrested.

This is a Q&A forum. You have not asked a question. Glad the cops were called.

Can you sue a court for a wrongfully issued bench warrant on there behalf? No.

This is a serious federal crime...................................

Candidly, none of us can tell you why your attorney did something. Ask them.

The odds of finding a lawyer to take on such a case for free are near zero.

Lawsuits are expensive and time consuming. Not worth it IMO.
