Guns are a great equalizer for the weak and elderly. The whole "call 911" crowd can note the inability to use a phone.
Is this a tinman tale of Dr. Doolittle's PushMe-PullYou in which the PullYou (aka gun) got the upper hand on the PushMe (aka telephone)?
I would like to hear more about the situation before rendering an opinion but I don't see how being able to fire a gun accurately is more difficult than dialing 911.
