The march to add spy drones to local law enforcement arsenal continues:

A small pilotless vehicle manufactured by Honeywell International, capable of hovering and "staring" using electro-optic or infrared sensors, is expected to be introduced soon in the skies over the Florida Everglades.

If use of the drone wins U.S. Federal Aviation Administration approval after tests, the Miami-Dade Police Department will start flying the 14 pound, or 6.35 kilogram, drone over urban areas with an eye toward full-fledged employment in crime fighting.

"Our intentions are to use it only in tactical situations as an extra set of eyes," said Detective Juan Villalba, a police department spokesman.

He acknowledged strong interest from law enforcement agencies in getting drones up and running, however, and said the smaller aircraft were particularly likely to have a "huge economic impact" over the next 10 years.
