>>>may be as many as four gunmen involved.
Whoa. Preliminary reports are often wrong and I certainly hope it's wrong in this case.
Meant to ping you to the ongoing 'perfume' discussion above. ;-)
I jumped over to FreeDominion to see if they had more news about this and they do have a thread going. Now it seems as if there was only one person who was doing the shooting and he was dressed in a black, long overcoat, from which he pulled a "long gun" and started shooting.
