A “DNA mist” that store employees can spray on unaware robbers: is this the future of crime-fighting? New York Times reports:
Rotterdam, the Netherlands — When the McDonald’s down from City Hall here was burglarized a few years ago, its managers decided they needed a new security system.
It was just about that time that local police officers were offering something totally different that they hoped would stem a rising tide of robberies that occur mainly in the immigrant neighborhoods of this rough-and-tumble port city. The new system involved an employee-activated device that sprays a fine, barely visible mist laced with synthetic DNA to cover anyone in its path, including criminals, and simultaneously alerts the police to a crime in progress.
The mist — visible only under ultraviolet light — carries DNA markers particular to the location, enabling the police to match the burglar with the place burgled. Now, a sign on the front door of the McDonald’s prominently warns potential thieves of the spray’s presence: “You Steal, You’re Marked.”
