Brazilian police officers can be seen attempting to de-escalate a group of individuals, when finally one officer had enough of their s!@# and throws a single punch, knocking one man unconscious.

Evaluating the situation, we see the officers pressing the individuals away to keep a safe distance. The individual in the white shirt continues pushing the officers hands away and getting into the face of his partner. It's unclear what is said, but clearly this officer was at his breaking point. As the officer shoves the man in the white shirt back one last time, he follows up shortly after with a hard right hook, knocking the man clean out.

If you have any context to add to this, let us know in the comments below. I'm sure the community would appreciate some translation of what is being said.
