Yeah, I guess so. If they were on the "stage" (behind the barriers) with Kirk then private security makes more sense. I was assuming they were mixed into the general audience when I first saw the video.

I'd be interested to see more angles just to confirm how close they were. It would be neat if a journalist could interview them too (not even out of suspicion, just in a "tell us what it was like" way) and confirm that they worked for Kirk. If they immediately fled to Tel Aviv then that would be cause for suspicion lol (unlikely).
