Hmmmm.. a vigilante that was a good shot could have killed all seven of them..
The news from that event could encourage a whole city..
NYC needs to be Charles Bronsonized... and Detriot, Chicago, San Fransicko and L.A. not to speak of Berkley, Ca, Madison, Wis, and Dallas.. O.K. and Boston as well..
Heck it would be blamed on drive by gang activity..
The vigilante would have serious cover..
