I actually had to look up what that word meant, and I watched the news clip that came with it, when they showed it on TV he said "Gee, Gobo" but for some reason, I don't know if they sped it up for the SCLC leader but it DID sound like Jigaboo. That being said, it's just a guy mishearing something, and having that in his head as he kept listening to it. It's happened before, I've done that with songs. Now, as far as them editing it out and the dad saying "If he didn't say it then why edit it out?" Because they don't want you to sue, and they don't want 90 billion other people thinking they heard it and having a bunch of either "tramatizing" or other things that can be put into lawsuits. Both sides are at fault here, one for mishearing it, the other for knee jerk reaction to them mishearing it.
