Intervening in a random street fight is a very dangerous thing to do. You don't even know the reasons why they were fighting - it might be a gang or drug related feud. And you could have been shot or even stabbed by one of their mates for intervening.
The only time I would ever intervene is if I saw someone being mugged in the street. Then there is a good reason to risk my life. But I would not risk my life if I saw two idiots fighting in the street.
