Eating a battery is not a reasonably foreseeable event that would occur with a high probability. It's something that can happen, sure. But doesn't happen that often even when they are left around. So I don't think anyone should be charged in that case. You can't protect against everything. But it's really easy to protect against leaving your kid in the car. And since that carries an extremely high probability of serious injury or death, people should be mindful about it and try to do whatever they need to in order for it to never happen. It boils down to risk and statistics. There are 100 ways your kid can kill themselves in your house every day. They could stick something metallic into an outlet and electrocute themselves or knock into something and a heavy object falls on them. You can't know that any of those things will happen at the moment they do, but you do know what is likely to happen if you forget your child in the car on a hot day. The cause and effect are proximate and immediate. That's why there should be culpability. It should be no different than how we prosecute the most serious errors on the road such as drunk driving that leads to a serious, possibly fatal accident or whether it's just someone who wasn't paying attention or was very tired and accidentally hit someone. We generally, but not always, charge those individuals. The prosecutors look at the evidence and if a driver made a serious/negligent mistake, they charge them. If the circumstances were one of happenstance and not a clear fault, then charges are usually not levied. Same logic should apply here. Yeah I said I forget things all the time but the things I forget are NOT part of the system I have in place. That's the point. The habits I have are to make sure I don't forget the things I really care about or absolutely need. So no, it will not be 99.9999% for those items - it will be 100%. In fact, my habits have caught me forgetting the things on the list literally hundreds of times over the past decade. It works and it always catches it.
