If they made a example of Ross, they should make an example of this agent too, but we all know lady justice in the USA is blind. Her eyes are covered so that she cannot see the corruption and injustice going on in the American Judicial system.
The agends are there to guard against crime, and then they steal money... How can a plea justify anything?
The thing is, they knew all about this when Ross was on trial, and they did not want to accept it in court. There are no double standards in true justice.
