Mr. Mallett Opposes installing new cameras in old trains.

"Zakhary Mallett, who represents communities in western Contra Costa and northwestern Alameda counties, says he’s opposed to installing surveillance cameras on BART’s current train cars. That’s because next year the transit agency will begin running its new generation of train cars, which will come equipped with the devices."  https://ww2.kqed.org/news/2016/07/19/top-transit-official-bart-needs-to-move-faster-to-install-surveillance-cameras

I agree that the money would be better used elsewhere.
