Spray DNA Lowers Crime – Homeland Security Newswire

When you think of McDonald’s fast-food chain, the term “high tech” does not immediately leap to mind, but surprises will never cease.

When the McDonald’s down from City Hall in the Dutch port city of Rootterdam was burglarized, its managers decided they needed a new security system. The Rotterdam police was urging local businesses to try something different, which the police was hoping would stem a rising tide of robberies that occur mainly in the immigrant neighborhoods of this rough-and-tumble 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.
