The vote came down shortly before 11:00am Thursday. The board decided to purchase 130 additional Tasers at a cost of around $140,000.
Currently, BART police officers share 60 Tasers. The purchase of 130 new Tasers will ensure every BART officer is armed with a non-lethal weapon.
The measure needed two-thirds majority from the BART directors to pass.
The issue of BART officers carrying Tasers came to light following the shooting death of Oscar Grant, an unarmed passenger, by a BART police officer on New Year's Day in 2009. BART police officer Johannes Mesherle said he accidentally pulled his firearm instead of his Taser when confronting Grant during an incident at the Fruitvale Station in Oakland.
Mesherle was convicted of involuntary manslaughter last year.
