Gonna charge the defense lawyer they tackled inside an open court room, against the judges verbal orders, with 3 misdemeanors over 3 months after the fact so they can take him to court and force him to plea it down to save his hide.
This is Juristprudence in the United States !!!
I think the purpose is two fold. First they want to keep the lawyer busy with his own defense rather than assisting his clients and secondly, they may be trying to use this to stall a civil suit against the US Marshall Service.
As is always the case, the process is the punishment when you run afoul of law enforcement.
