You could be the baddest guy on the planet it does not matter in the street, the only thing is the guy who lands the first punch, how many times have you seen two guys arguing and one hits the other and knock him out, because in the street nobody says are you right lets fight, the punch comes without warning.
Which means, that if you are the baddest guy on the planet, you should punch EVERYONE you see on the street without warning, to prevent someone suckerpunching you.
Doing your daily jog, BAM! SLAM! WHAM!
Walking with the Dog, BAM! SLAM! WHAP!
Buying Groceries, BAM! SLAM! WHAP!
etc
Then you will NEVER be suckerpunched, since YOU will ALWAYS strike first!
