Well, I gotta agree with 5.56X45mm's opinon. I think it is against the 2nd. Well, it will be long discussing. Program the gun or not? If I have a wife and a kid. I got the smart gun. The smart gun is upstairs in my bedroom. My wife sleeping in the bedroom. my kid sleeping in other bedroom on the second floors. I'm watching the TV. the home-invader come into my house. I noticed he have a gun. he shot me in the leg. My wife is upstairs, heard the shot. So, the kid is....heard the shot. She gotta make sure the kid is alright. She heard the stepping going up. She notice it's an insane bad man with a gun. She grabbed my smart gun and *click*. My wife or kid would be killed by an insane bad man. So....I'm not going support the smart gun. (it is just fiction story, people.)
