An New York uniformed police sergeant that I have known for over thirty years, a personal friend, told me of his experiences with a street crime unit.
This unit was formed to work 6PM-2AM Wed-Sun on the blocks around a large low-income housing project. The population was largely African-American. In the months before the unit was deployed crime in the area had spiraled. There were a lot of drugs being sold, large numbers of youth congregating in the streets, assaults, robberies and several shootings, two of which were fatal.
The sergeant was deployed as commander of a four-person street unit. Himself and three uniformed patrol officers. He told me he started having problems with the three cops right away. He said they were needlessly belligerent with people, overly confrontational. He had to referee many an argument and, in his words, "It was my cops that were usually the problem."
One of the factors was the relative inexperience of the officers he was assigned. The sergeant tried to get some of the veteran officers to volunteer but none of them wanted to do it. He said, "Because it's all foot patrol. The older guys want to be in a car."
He said he tried to explain to his guys, that the street people they were interacting with were very sensitive about being shown up. He said to them, "You try and push these guys around in front of their pals, you're going to have problems."
The unit did make an enormous difference. Primarily by stopping drug sales on the street, that changed the whole dynamic. People had little reason to congregate, there were no longer squads of drug addicts hanging around and gradually everything calmed down. Then the police unit did little more than maintain a presence. Eventually the police department reduced the assignment to Fri-Sun and then the officers involved were redeployed altogether to regular patrol. I think occasionally on random weekends they assign a sergeant and one officer to the blocks around the projects, only not on foot as previously but in a police car. That way they could also cover medical emergencies, traffic accidents, back-up other units, etc.
The point is, with the proper management a lot of the problems that have plagued SAF could have been minimized and maybe there would be no lawsuit.
Make no mistake, the enhanced patrol does make a difference. SAF has an effect. It undoubtedly does reduce the number of weapons carried because there is no way for anyone to know when they might be stopped by the police. But the way the stops were conducted gradually eroded the community support. To the point where people were complaining that the police had become more of a problem for people than the criminals.
