Working off his plan to house the city's homeless in vacant buildings, Manhattan Borough President Scott Stringer outlined how he would go about collecting a census of the city's empty buildings: hire the jobless!

"The City already dispatches volunteers for its annual street homeless count, so this approach would not be without precedent," he said. "And, to be honest, counting vacant lots isn't rocket science. It would require a minimal amount of training." Training that would include learning to identify when a person is in a room?
