I find the excuses against smart guns really silly. No offense on this one, but the idea is to improve safety, not perfect it. If someone steals your smart gun, they still have to hack it before they can shoot you in the head with it, that may be something that can be done quickly, like in ten minutes or less at some point, but they still can't shoot you in the head with it then and there. Likewise, if it takes two seconds instead of one second to unlock to protect yourself, then that may make a difference, but more likely it won't. With a quality smart gun, it will unlock quickly and in a manner you are comfortable with using. The idea is that we should have a MASSIVE push towards them as an option, not an active effort to stop them from being the norm in the USA.
That six year old wouldn't have done crap with a smart gun is my bottom line point.
All the training in the world becomes meaningless when carelessness is removed from the equation and a parent could leave a fully loaded, fully usable, smart weapon in their infants crib and it would never be able to go off.
The reason the mom of a six year old needed a gun is very much her business. The fact that she allowed her six year old to get his hands on it is pure recklessness and led to a tragedy that should be able to be easily avoided, and I believe smart weapons would solve this issue for a ton of people. Some will never use them... and so what? Who cares if Johnny Truckdriver doesn't want a smart gun? Alice Momofthree should still have that option.
Smart guns remove the opportunistic usage, mishandling usage, and easy unauthorized usage from the equation. It becomes seatbelts or airbags for a gun. It won't stop death, murder, or even occasional accidents, but it should be heavily embraced.
