There's longstanding animosity between kids in the NYCHA building where they reside & another NYCHA residence.
So the cops think it would be funny to drop him off at the other complex.
He was dropped off in the middle of the complex, where there was only one way out. He had nowhere to hide.
He could have been killed. And the cops must have known this. And it was a joke to them.
But Black kids - who they presume are in a gang (he's not) because they live there - are disposable.
And if he were killed, would his death even be traced to them?
How many children die & we never really understand why?
Things like this are truly funny to them.
But that's a whole other thread.
