“A BART police officer was fatally shot by a department colleague Tuesday afternoon during a probation check in the East Bay, according to the Alameda County Sheriff’s Office,” kron4.com reports. “BART officer Tom Smith [now deceased] and several other officers had forced their way inside one of the units during a probation check when the shooting occurred. The subject of the search was on probation for crimes committed on BART property and was not at the residence at the time of the incident. Both officers were wearing bullet-proof vests, according to officials. Alameda County sheriff’s Sgt. J.D. Nelson said he assumes that the officers had their guns drawn as they entered the apartment but that the details of how or why the officer’s gun went off remain unclear.” Went off. Yeah. Sure.
