How about surveillance, as in known drug dealer in the area, observe dealer before making an arrest. if spotted before hand have him either run, or shoot out,Or give up, or when trying to arrest him without a weapon pulled in normal arrest have him resist you and run. And when run by any way possible as in foot pursuit turned to car jacking turned to high speed pursuit. etch.
Would be cool to have an event where it would have multiple out comes just to keep it interesting.
