Sure Bill, it was smart phones. How about given how unlikely it is to ever need a loaded gun for self defense in your home that you don't have readily available loaded guns in homes, much less your damn car, with kids. And if you do and your kid kills you (best case scenario) or themselves then you get to go to jail? It's a choice, right? And, while the article didn't mention it, I'll guess it wasn't a Barrett .50 but maybe a pistol. And before a revolver that might have too hard a trigger pull for a 3 year old I'd guess a Glock without a safety. And no, I don't consider trigger safeties to be safeties.
Too many easily available guns and too many dipshits is the problem.
