BART PD has been famous in the Bay Area for about 6 or 7 years for being a Troubled Department.

They unprovokedly shoot a guy proned out on the floor.
BART PD has been "troubled" with reckless killing since the day they were created.
One of their first public services was to shoot a local world class neurosurgeon through the head in the Daly City station because he had a holster on his belt.
His cellphone, in the early days when they were fairly large.
BART started out killing San Francisco's finest.
