He might not have been actively a physical danger, but he did make it physical. He was told no and still tried to push through. He then gets angry (indicated by him telling them not to touch him despite them simply standing firm). He then reasserts his intent to go past them. He gave every indication of escalating the situation. That’s a definitive threat. I don’t think they should have to play his stupid games and just push him back until he becomes more and more threatening.
