Seattle Police Department blog:
When a car is reported stolen in Seattle, employees in the Seattle Police 911 Center will tweet the color, year, make, model, body style and license plate of the stolen car. Twitter followers who spot a car that has been tweeted as stolen on “Get your car back” should call 911.
That’s pretty neat, they are using the 911 operators to tell you if the car is still stolen, and hopefully they tweet when the car is recovered too. Great use of the technology.
