Big Sal Miciotta could knock out a roomful of guys

Abit off topic and questionable if OC related- but the morrocan brit who carried out the world's biggest heist at time "lightning lee Murray". He fought once in the UFC and couldn't go back stateside due to visa issues stemming from beating a fellow motorist who tried to attack him- into a coma

I've been told firsthand accounts from people who saw him knock out a team of bouncers single handedly

Leonetti was never a street fighter, he got tapped out by that black prisoner had someone not jumped in to save him
