On a similar note I am not telling people it can't happen and doesn't make sense.
All I'm saying is that in a majority of cases I think these tragedies preventable - if the parents just stop, take a breather, and don't engage in risky behaviour. Like Harrison in the news article - I will go as far as saying he was negligent and I 100% support him being charged. That is my opinion, and to date I haven't heard anything that is going to make me change it.
It's not only about ensuring parents who make mistakes feel better. It's bigger than that. It's also about justice for the kids and preventing similar tragedies from happening again (which IMO won't happen until parents at least accept some responsibility for ensuring they are not engaging in risky behavior while their kids are in their care).
