because most americans are petty snitches and will tell on you over their childish cop fetish. even if you are a white man and beat up some stupid coon, other whites will tell on you while finger fucking their own assholes. so any fighting must be done with no witnesses. also it you will probably have to take their phone away from them too since they like to tell that way too. not very manly, but that's american, "men" for ya.
