Shocked...!

It was late and dark, I was with a work buddy at a bus stop, waiting for a bus that wasn't loaded to capacity to go home after a long difficult day. We were sharing various bus jokes and laughing at random things when suddenly, a guy jumped in front of a three-wheeler and I looked away, imagining the worst. The bus stop seemed to have had stopped, everything was quiet except  screams, except, those were not of pain but of anger. "Get the hell out of there, get out of there, you whore!" my head turned to look at the guy who, moments ago, jumped in front of the moving threewheeler screaming and madly swinging at a cowering girl in the backseat. When I looked more closely, there was another guy in the back seat with her. Meanwhile, the guy outside kept trying to drag the girl out in to the pavement and the three-wheeler driver kept looking ahead oblivious to world war three going on in his backseat. This went on for about five minutes and the whole time, the guy outside the three-wheeler kept throwing threats and blows at the girl while the guy inside
kept saying " stop stop, let's just talk about this, please get in!". In the end the driver finally decided to drag his fat ass out and intervene "sir please get in, we'll go somewhere quiet and talk"
(Weird, maybe that's what he was trying to put together for so long). Eventually, Kung fu master there, finally decided to quieten down, get himself half dragged in to the backseat and allow to be zoomed away out of sight.

The crowd dispersed while my friend and I were left with open mouths. We missed a couple of empty busses too as he pointed out later. This happened a few weeks ago, and I still don't know what to say. All three of them were good looking office types and raised many a theories among the audience, which mostly justified the karate kid's actions. (They were fantastic viewers by the way, and managed to maintain absolute silence throughout the whole scene and nobody - even the body builder type guy in a muscle tee - intervened.
Maybe the grl was caught red-handed while cheating, or may be it was a weird misunderstanding of some sort. It's so not my business, but still in my opinion, people should try not to resort to violence and try to solve problems in a rational and more civilized manner.
And a note to the girl-  I don't know the real situation but, If you were cheating, I just hope you won't cheat on anyone else and if it was all just a wrong-place-at-the-wrong-time incident then, know what you're dealing with (your guy).
