Well as the brotha code states: *puts reading glasses on*
...If by any chance you and or you friends happen to be chased by any among these (Dogs, Cops, Gunmen, and or All of the above) you have a chance to out run your partner and leave them...but since it is you friend you mst turn back within 20-25 yards before making an attempt to stop.
So basically NO i wouldn't I'd just out run him then if we run into a building i'd hold the door open waiting with a glock in my hand picking them off if they get to close.
