If a man starts a fight with a headbutt he doesn't give a fuck about his life. Just stay down and play dead because he really doesn't give a fuck about your life.

The other dude was extra spunky and could have had a weapon. Better to start and end the fight with a headbutt. He can't reach for the weapon if he's been head-butted unconscious.

Given the proximity, he was left with little choice. Perhaps a knee would have worked but he is large and had little space. This was a well thought out attack.

The bearded smaller man had been causing a lot of trouble. The man who restrained him was an off duty London police officer. The full incident lasted 20 minutes during which the smaller man kept struggling and being verbally aggressive.
