Since the police shooting of Michael Brown and the response in the streets, militarization of the police, especially with surplus military hardware like armored vehicles, has been a hot topic, both in the news and in Congress. And that‘s a good thing.

But the equipment we can see on the news isn’t the only thing flowing from our military to local cops. Alongside armored vehicles and guns, local police are getting surveillance technology with help from the federal government. And while we don’t know the full contours of that aid, what we do know is worrisome and should spur further scrutiny, both locally and nationally.
