Check out At-Scene. I don't know if it's available yet or still in production, but if it's not out yet it should be soon.
I'm a little bias.... U.S. Cop app for iPhone/Andriod
Check out this new Android/Iphone App called V.I.S. its a vehicle identification system. It's made for quick vehicle recognition especially for the hundreds of new models out there. It's only 0.99 cents. You can use it to interview victims too. It can confirm or rule out suspect vehicles.
Check www.at-scene , the Andriod app is called iCrime Fighter, its an excellent police tool. The andriod app launches on 09/19/2011!!!! iphone app is already out.
I started with an Iphone app and now I've gotten into Android development. How many other officer/ app creatures are out here?
