Hypothetical situation: A law with a perfect enforcement rate was written. The law punishes firing of a weapon by anyone other than the owner with a $1 million dollar fine and 20 years in prison. It is intentionally draconian for the purpose of this thought experiment.
Now, consider someone who must posess a firearm (the reason they must is irrelevant, so assume that they must own one). Also assume that they are allowed to implement ONE method of control which exists or is possible today while still keeping the firearm available/useable to the owner. (viable options: Smart-tech, Safe, Triggerlocks, etc. Non-options: encase in concrete and sink in ocean, etc)
Given the hypothetical situation: Draconian punishment for non-owner discharge, requirement to posess/operate a firearm, only allowed one method of control.
What would you pick as your method of control to limit your exposure to the draconian punishment? Would you pick the smart-gun fingerprint reader, a safe, a recurring 'talk' with the members of your household, etc.
Personally, I'd pick the option for a gun-safe with an X09 style lock. I'd not trust a trigger lock (vulnerable to theft and drilling), nor smart tech which could be circumvented, especially if the gun was stolen.
