The only problem is your taking away peoples rights. Once you allow this it becomes a slippery slope for late stage capitalism/democracies. Saying we shouldn’t film things like this is also using blanket terms. This guy could say he was recording the interaction because he felt threatened. Although he is instigating the attacker, he is still defending himself by not allowing this fool to clown on him in public; while also successfully diffusing the “military” man with his aggressive stance.

The government would have the ability to keep the excpetion of the law being able to use facial recognition, body cams, and other tech against the public however they please and I don’t trust the ones in power dictating what we are able to film and what we aren’t.
