If your not ready for a confrontation between these people its safer to let them pass and then be on your way, U never know what could piss them off and then they'll follow u or try to run u off the road..

If the cops were around those guys would've never tried this in the first place. Its not like the police standby and watch this kind of thing.

Unless its a closed area by the cops etc.. Like when the Football matches end an Qatar is victorious or something.
