Express skepticism about the use of slogans and advocate for a more nuanced approach when dealing with armed assailants. Suggest that in the case of this particular incident, the use of a shot in the leg would have been sufficient.
Slogans are a lousy guide to all situations. It is wise to "shoot to kill" an armed assailant...for the simple reason he/she might be able to get off a shot or a stab or something...but this guy was not, apparently armed. A shot in the leg was sufficient.
