This article does a much better job of describing what happened. Does not make the cop look better.

Authorities were heard asking the man – “May I help you, sir?” – at first but as soon as he was engulfed in flames they started yelling at him to get down on the ground. They even drew their guns on the burning man before someone pushed them to get fire extinguishers to extinguish the fire.

Edit: What damn freedom in those moments though. I mean you can yell at the guy engulfed in flames all you want with the threat of ending his life, but he knows he’s already ended it.

Fuck you I won’t do what you tell me, indeed. I wish the man had chosen another way to protest, but WTF does he give a shit about threats from a fucking cop at that point?
