i managed to find https://mashable.com/article/how-to-shut-down-boston-dynamic... :
> Could one pull the battery out while Spot was in use? We asked Boston Dynamics this, as well as what would happen both to Spot and to the person doing the pulling, but received no immediate response.
> In addition to the removable battery, there are two buttons located on the "back" of the robot that may be of (again) theoretical interest: the power button and motor lockout button.
ie, rather than go around corner with a gun drawn / risk of shooting someone / getting shot - you'd have spot walking 5 feet ahead, stick that weird neck thing around corner. Give folks more time to eval etc vs having to be ready to blast folks away.
So not really a concern around kill switch etc. If someone is around the corner pulling kill switches - you probably already have imagery to work from.
That was so embarrassing.
