Bell was killed by a theory. The theory is the result of the Sullivan law. It goes like this:
When you have a social culture that in which saying a gun exists means that it physically there (even if it fact it does not), you, as a LEO, behave as if it is.
Bell was killed because somebody heard that somebody in his group of 3 had a gun. Nobody saw it. He and his buddies left the building - disengaging from the conflict, but because the NYPD operates under the mindset of the theory, they wanted to arrest him.
The arrest was attempted outside of the building and down the street/around the corner by plain clothes cops, in a method that given that he was tired and had had a few, he initially acted as we would - he assumed an attack/robbery and tried to escape.
51 rounds were fired into the vehicle, hitting everybody in the car, and killed Bell. One of the cops let fly 31 rounds - emptied his gun, reloaded a second mag, and emptied that.
No gun was found.
The judge that heard the case - it was non-jury - and indicated that
"It was necessary to consider the mindset of each defendant at the time and place of occurrence, and not the mindset of the victims.”
The cops - being the defendant(s) - were a prisoner of the theory....
