The rally was organized in the wake of 13-year-old Scotty Scott's shooting death last Friday evening. Two others were injured in the incident.

Organizers are asking anyone who saw anything that night to come forward.

"Everybody knew him. Everybody knew him,” said family friend Joann Coutourier. “If you didn't know him, you knew his mother, you knew his sister, you knew his cousin, you knew me. Somebody knows something, it's inexcusable."

Leaders are demanding that the community help in making its neighborhood safe.

"It is unthinkable and unacceptable that our summer has been punctuated this way,” said City Council Speaker Christine Quinn.

The group 100 Blacks in Law Enforcement is offering a $1,000 reward to help capture Scott's killer. The organization plans to have eyes and ears on the street.

"Enough is enough,” said Michael Greys of 100 Blacks in Law Enforcement. “We are tired of these senseless murders in our community. We are going to initiate a community patrol starting this Friday coming at 5 o'clock at 144th Street and Adam Clayton Boulevard."

Police are offering a $12,000 reward for information, hoping it will lead them to the shooter.

Scott's family and friends not only want to know who is responsible, but why it happened.

“We walk around here with these tags and with these shirts, because this is all we got right now," said Coutourier.

100 Blacks in Law Enforcement is taking its plan outside of Manhattan. The group says it is willing to train volunteers all over the city how to conduct patrols.
