Curious, the chink guy push ah neh first but ah neh throw the first punch. Dunno which one is the wrong move first. Because I know in sinkie not sure other countries, who make the first move of the violent confrontation is wrong. Pushing is also can be considered.
Retaliation is also wrong. So fight back also wrong. But another they also see size, the chink is obviously bigger size and next do they have martial arts records and base on the vid is no. I also curious which marital art best to stop fight and it seem like judo or wrestling will be better to pin the person down.
