Madison is considering a measure that would require all convenience stores in the city to have security cameras.  Mayor Paul Soglin proposed the ordinance in response to a number of armed robberies.  Madison’s Public Safety Review Committee is scheduled to discuss the proposal today (Wednesday). The ordinance calls for the cameras to be focused on the front counter and cash register area of the store, and would need to show a high-quality image and a time stamp that the police could use. Stores would also be required to post a sign saying that customers are being recorded.
