It's more than that, Tom Servo.
Wide Receiver was shut down basically because of the gunwalking. When the new administration came along, they decided to dig the case out and pursue it, despite the gunwalking. This was (not unreasonably) seen as a green light by Newell, who had been in charge of Wide Receiver gunwalking. He figured it was OK again when they restarted the WR prosecution.
The two are closely related in more ways than one, and only Lanny Breuer was able to avoid seeing any connection, and he was only able to do that when it was really, really politically convenient.
