Your friend needs a criminal defense attorney ASAP to represent him on the motion to revoke hearing. The attorney will need all the documents from the D.C. incident. Get counsel immediately.
I am trying to give you a general answer to your question. We do not have an attorney-client relationship by this response on the avvo website. I have not been retained to represent you. I am licensed to practice law in Kentucky and in federal court in this state and the Southern District of Indiana. You need to seek legal advice from an attorney licensed to practice in your area..
For the probation violation hearing your friend needs an attorney. How the court deals with the violation will depend what he is on probation for. He needs an attorney.
ANDREW ROBERTS CRIMINAL AND TRAFFIC TICKET DEFENSE ATTORNEY
Your friend needs to be represented by an attorney both in LA for his probation violation and in DC. He may be facing federal charges in Washington. The sooner he is represented by counsel the more time an attorney will have to properly prepare a defense and start working on his case.
