So what exactly did the 8 year old boy sat in the back of his parents car do wrong?

Nothing, and that is very bad luck. My heart breaks for the kid.

But unless you are suggesting that laws should be not applied to those with kids, I am not sure why that matters? What do you suggest? I cannot wait for "kid" to be a number one accessory to bring to a heist then.

Again, what law was broken here? By anyone in the car? I'm struggling to understand how this wasn't outright execution.
