BRYAN PRESTON: Who Is Responsible For NBC’s Zimmerman Edit? We Have A Name. “I wrote earlier that there is no way that NBC’s Zimmerman was an accident or error, as the network claims.

NBC’s Zimmerman edit was deliberate, done in a network editing studio at the specifications or orders of a producer who in turn answers up a chain of command that ends with the executive producer of the show that aired it.”
