I think he was set up by the authorities.

Why? Because Askew called the FBI earlier that day. Probably to let them know that everything was going as planned.
The only reason I say this is because Askew was suppose to be running for city council but he did not raise any money. He had no supporters. On the night of the shooting, 1 of Askew's neighbors said, in the past, Askew was always wild and had a reputation of being crazy in the neighborhood. She said she grow up with him and was not surprised at all. He could not have competed against Davis if he tried.
I did not hear Askew had HIV but I heared he had his will sitting out on the table when the police searched his house.
Davis' body arrived at City Hall at noon today.
He represented my district in Brooklyn and he always voted for the people. I can't find his voting record but...
Davis asked Toys "R" Us to stop selling toy guns because 2 children in the New York area were shot, 1 killed, by police officers

who thought that the toy guns were real.
That same month, he asked MTV to stop playing violent video's between the hours of 6am & 11pm.
The councilman wrote: "Too many youths graduate from juvenile detention centers, go on to jail, then go to prison upstate. We have to stop that cycle. Something is wrong when a detention center fails to rehabilitate but instead leads a youth into a permanent life of crime.
Mayor Bloomberg has put $64.5 million in the budget to expand detention centers. I feel the money should not go into detention, but into prevention." (James Davis March 22, 2002)
He fought the last fare hike that NYers are currently paying. $2 one way is the current fare. $7 for an all day pass. It's outrageous. He fought to keep the token booth clerks. He felt that they were the eyes and ears of the train system. As a former Transit Policeman he would know.
He even visited my church once. Holy Trinity Baptist Church. He was a good man. I wonder who will replace him.
