<< Some time ago I heard about a new safety measure for guns, which involved some kind of chip which would only enable the use of the gun if the owner was holding it. It used fingerprints for identification. >>
Last I read on it, they were still working out some kinks in that. Just imagine the lawsuits that would pour in, if someone was killed by an attacker because the gun would'nt fire due to some electrical or signal problem.

I hope you and your family will never need one. They rarely need to be used, but I am 24 years old, and they have saved my families lives twice so far by owning one.
