I think finger print scanning sounds like a decent idea.
Yes, When the bad guys show up, I can fumble with my gun safe combination, look for the key to the trigger lock, attempt to load the gun, all while being scared to death, and then hope that the electronics work, and the battery has not gone dead. Rack up another one for the bad guys. But, maybe the cops will catch them, and maybe they might go to jail, if some asshole judge doesn't think they murdered me because they had a bad upbringing, and turn them back into society.
Sorry, twinkles. I will worry about my gun safety, and the safety of my family, and that does not include any liberal/socialist complications to my ability for defense of myself and my family.
