There has been a 2-second edit at about the 6:00 mark. I think that's where he said they celebrated 9-11 but it appears to have been erased.
Here’s the transcript. The Drew guy said SOMETHING, but you’d have to find another uncut version to find the missing words. Maybe it’s nothing, but I don’t see any reference to 9/11 elsewhere in the entire video, which is what the title implies.

It’s sickening, of course, in the wake of the shootings, especially, to hear what these folks are saying just, you know, not too may blocks from where I’m sitting right now. How can they get away with this?”

Drew Griffin, Special Investigations Unit:

How could they be on the web saying this stuff and right after ______________________ hours they were praising this attack. It’s protection under the 1st Amendment. That’s what’s protecting their speech. And LE guys who are watching these guys... blah, blah, blah..
