Limited skill, despite the carnage he has managed to create. Ought ta get a real squad of snipers set up to take him down. Not as insane as it sounds considering the area he seems to be staying in. 20-30 2-man teams rotating areas every couple of days. Cover populated areas that the rogue seems to be targeting.
Should be able to bring him down within a week or so.
This may already be happening, and of course, they wont say. There is probably a good chance that the killer(s) may have already pre-selected target locations. If so, the sniper may just be driving around, from place to place, seeing which one is safe at that time, and takes a shot. That seems more likely than someone completely randomly selecting locations at the spur of the moment.
Then consider this. He stated that, "I am God." Gotta tell ya, if you think like an ecco freak, that could mean that he is acting as God's hand, desiminating justice as if by His will.
Just think what these users of carbon emitting vehicles are doing to mother nature! Have they been judged and found wanting? If so, expect this guy to get the same treatment as the Uni-Bomber. Oh he's a poor fellow who meant well. We can't give him the McVeigh treatment...
Hey, it's a thought.
