Sure, but people making this argument tend to imply that a gun is the only effective way to deter or disable specifically an attacker with a gun. No one says police should carry guns to deter knife wielders and a Kevlar vest would seem to provide more protection against someone with a gun who's at the end of their rope/too strung out to care. This line of reasoning would make more sense if life was a TV show and every armed interaction was a Mexican standoff, but in reality most criminals with guns are already far from being rational actors.
