FORT LAUDERDALE, Fla. (CNN)-- Police officers in Ft. Lauderdale have a new weapon in their arsenal to fight crime, and it could be coming to a city near you.
It's called SmartWater. The product is a forensically encoded liquid that comes in a bottle. Businesses owners and residents can use it as an identifying mark on their belongings, or they can spray it on an intruder.
The residue lasts up to five years and only shows up under a ultraviolet black light. Police can lift samples of the residue off a suspect or possibly stolen good and match it up with the right SmartWater owner.
The mayor of Ft. Lauderdale appeared excited as he introduced the product.
