It was grandstanding, to make the news and enhance Mumford's  career - "Mumford goes to the mat for his clients."  Then the dopy posse comitatus Neanderthals, when they get afoul of the law, will say "I want that Mumford guy, he goes to the mat for us 'Muricans."  Mumford is sharp - since the acquittal of the Bird Sanctuary Seven, Mumford foresees a rising number of armed "militia" insurrections, and they will all need a lawyer who will got to the mat for them. This is "Murican" enterprise at its (least) finest.
