The American Civil Liberties Union has released documents confirming that police license plate readers capture vast amounts of data on innocent people, and in many instances this intelligence is kept forever.
According to documents obtained through a number of Freedom of Information Act requests filed by ACLU offices across the United States, law enforcement agencies are tracking the whereabouts of innocent persons en masse by utilizing a still up-and-coming technology.
License place readers are among the latest items being regularly added to the arsenal of law enforcement gizmos and gadgets, but documents obtained through the FOIA requests have prompted the ACLU to acknowledge that safeguards that would properly protect the privacy of Americans are largely absent.
When a police department deploys license plate readers on top of patrol cars or at fixed locations, it lets officers see a snapshot of every vehicle that passes by a particular point. From there, that information can be matched against a database that contains automobiles involved in criminal investigations or cars whose owners may already be in trouble with the law. According to the ACLU, though, the data that’s collected and routinely stored reveal much more than the location of suspected scofflaws.
