After Jordan Neely's martyrdom, who wants to stop a cleaver-wielding man on the BART?

Fortunately, in the case of the BART cleaver-wielder, although the injured man was taken to the hospital his cleaver injuries were not life-threatening. But this was the scene, and if you read my post from yesterday about Neely and the behavior of subway riders who feel threatened, you’ll see the connection …

I wonder – in a case such as this, where the perp is armed and has already hurt someone and clearly intends to hurt more people, if an armed person had shot and wounded or killed the perp, would the shooter have been arrested?
