I think the supervisor acted correctly. If you're traveling with Uncle Frank who is getting patted down, it's between you and Uncle Frank whether or not it's appropriate to video the pat-down. However, in this case, seems to me that Mike Ditka didn't know the clown who was taking the video and seemed that he didn't care for the clown taking the video.
I think the supervisor did the right thing to ask the person to stop videoing. I think the supervisor should have also had the LEO escort the individual off the checkpoint immediately. But I don't know the totality of the circumstances.
I know that I'll get flailed for this. So be it. But this would apply to anyone else regardless of celebrity. If you're taking a video of someone else being patted down without their consent (e.g., it's not your Uncle Frank or Aunt Carol), then I'm going to ask you to stop. If you don't, then I'll have the LEO escort you off the checkpoint.
