With something like that, I'd go for the torso, but you can aim for the abdomen instead of the chest, just to be safe.

[She's assuming he means "the preferred spot to not accidentally kill someone", since most people choose non-lethal weapons for a reason.]

Using regular tasers you can go for the legs as well, but that's easier when you're in closer range. If we're on missions your first concern should be protecting yourself.

[Regardless of whether that means accidentally killing someene, which... probably isn't advice Bruce would approve of. But screw that.]
