The guy was unstable yes, but he also looked super liberal. It's tough to articulate, but it exists nonetheless, it's like asking what strawberries taste like. Perhaps I can't articulate it but that doesn't mean nobody can taste them or the taste doesn't exist. Some facets about him that I don't care to enumerate gave me that impression. He was trying to appear crazy yes and he did brandish a knife as well.

You are being far too charitable with him. He essentially committed assault by creating the impression that andy was not physically safe and that he may use a knife against him.
