In These Times spoke with ACLU Senior Staff Attorney Adam Schwartz about legislation the ACLU supports, Senate Bill 1753, which will place modest regulations on the use of Automatic License Plate Readers (ALPRs) by Illinois law enforcement. ALPRs are cameras mounted on police cars which scan and record the license plates, and store the dates, times and GPS locations of every vehicle in its vicinity.

The potential of this technology to enable police to undertake widespread, systematic location surveillance poses real concerns about privacy rights, which the bill aims to redress.
