<i>Parent opposes a device that would record the timestamp, location, and owner of a gun when fired. This information should definitely not be secret in a self-defense or other justified killing.</i><p>Parent, that is, myself, does not oppose on those grounds, as I explained in reply to you.  I don&#x27;t think it&#x27;s constructive to imply that in a reply to another without replying to me.<p>And come to think of it, I don&#x27;t want to have to explain to the state <i>every</i> time I fire one of my firearms.  Especially seeing as how I&#x27;ve done that over ten thousand times without, you know, actually shooting anybody.<p>I would hope you could see the potential for abuse, for a chilling effect on good things like practicing with your firearms for proficiency.
