Officials with Bay Area Rapid Transit say only about 20% of BART commuter trains have working surveillance cameras.
The San Francisco Chronicle reports BART detailed exactly how many of its train cameras work in response to a public records request that newspapers filed last month.
BART said Tuesday that just 22.6% of the cars had working camera systems.
BART says that it is replacing its entire fleet of trains and that every car will be equipped with cutting-edge cameras producing footage that can be watched live from a central monitoring station. Those cars are expected to arrive between 2017 and 2021.
The Chronicle revealed the decoy program after learning BART had failed to film a Jan. 9 fatal shooting of a man aboard a train at the West Oakland Station.
