Annapolis, MD – The state Senate gave preliminary approval Wednesday to a bill that would limit when passengers’ conversations can be recorded on public buses and trains.

The bill was spurred by the Maryland Transit Administration’s practice of recording video and audio on hundreds of its buses. The legislation would ban that type of “indiscriminate mass surveillance” of transit riders, said Sen. Robert A. Zirkin, a Baltimore County Democrat who chairs the Judicial Proceedings Committee.
