As drones become cheaper and more reliable, it was only a matter of time before they were part of law enforcement. 

MyStateline - The department plans to unveil its fleet on Wednesday during a demonsration. The drones will be used to investigate serious and deadly car crashes by allowing the department to capture video and pictures that would normall take hours to do on their own.

Sounds pretty cool. Anything that speeds up the accident clean-up process is alright by me.

Oh, and if you were worried that this was another expense that the city shouldn't have shelled out for, you can calm down.

The drones were donated by Illinois Drone-One, Inc.

That's very nice of them.

So next time that you think the coast is clear to do something you probably shouldn't take a look up in the sky. There might be someone watching you.
