How an underfunded, understaffed crime lab in Hamilton County, Ohio manages to operate:

“On our tour we stop first in the trace evidence office, where analysts look for hair, fibers, paint chips, and other material left at a crime scene. The firearms office, which has a backlog of about 350 cases, has outgrown its own room and its machines have spilled into the trace evidence room; as a result, whenever trace evidence analysts have to look for gunshot residue—say, when they’re scouring a suspect’s garment to see if there’s any indication he fired a weapon—they must move the material two floors away to another office, to avoid contamination during testing or examination of the gunshot residue. The hallway outside is lined with microscopes and printers, and a folding ping-pong table nearby is pulled out whenever a large item needs to be spread out and examined.”
