The American Civil Liberties Union (ACLU) has launched a nationwide campaign to assess police militarization in the United States. Starting Wednesday, ACLU affiliates in 23 states are sending open records requests to hundreds of state and local police agencies requesting information about their SWAT teams, such as how often and for what reasons they're deployed, what types of weapons they use, how often citizens are injured during SWAT raids, and how they're funded. More affiliates may join the effort in the coming weeks.

Additionally, the affiliates will ask for information about drones, GPS tracking devices, how much military equipment the police agencies have obtained through programs run through the Pentagon and the Department of Homeland Security, and how often and for what purpose state National Guards are participating in enforcement of drug laws.
