It was undoubtedly a dumb thing to do but the implied suggestion that he was being threatening with the knife seems pretty far from the reality.
As said, it looks like a multitool or something with a pretty small blade. Probably not the wisest thing to take to the football (although it was a night game from what I remember so maybe coming from work) but perfectly legal.
I think it's any locking knife regardless of size and/or a blade over 3", neither of which appear to apply to that one.
I'll repeat, it was a dumb thing to do but suggestions that he was threatening the guy or that he was the one who should be in jail just don't match up to the video.
