Sometimes it is best to just report the incident to the cops and let them handle the situation. I am sure he would have been safe and the miscreants would have been caught if the cops were called prior to this man jumping in to handle the situation. Of course one's response depends on the gravity of the situation.
didnt he ......but I ve heard news of this sort from friends and family in places like U.S....where the intervener was stabbed and killed ......another one in Aus when the guy was later tracked down by a gang , cornered in an alley, beaten and hospitalised.....
