Totally Irresponsible
I am seldom surprised at NBC's behavior -- after all, this is the network that ran the exploding pickup truck story, only to admit later that it put model rocket engines in the fuel tanks to ignite the cars during simulated crashes because the they weren't catching fire on their own.
But NBC's editing of the Zimmerman 911 tapes to make them more inflammatory really sets a new low. The country was practically on the verge of race riots, with groups actually posting dead-or-alive bounties for Zimmerman, and NBC purposefully edited the tape from neutral to incendiary?
