"Could" is the operative word here. I heard that the prosecution may think Obama inserted himself into the witness list by negotiating this deal and playing hug and kisses with the deserter's mom at the White House and if there is a chance of him being forced to testify he can either pardon the deserter or claim immunity and refuse to show ...maybe leading to a dismissal.
I wonder if this General Abrams is any kin to the former Creighton Abrams?
