Greetings all, I took San Soo for about 2 years by accident at the travis air force base I can not remember the name of my teacher but he did it for free, and practiced on my own after i moved for years, From what he taught us, and from what I got from the style is not all are thugs. As everyone knows San Soo is meant to end the fight as soon as possible. I have used san soo a number of times in a "fight" if that's what you want to call it. It was more like it was me just getting the guy on the floor or hitting pressure points so they screamed like little girls. (my teacher had us study pressure points I don't know if that's how all do it)
