My five-year-old has a better sense of responsibility than he does.
He strikes me as the sort of person who believes whatever he's thinking from moment to moment, even if those thoughts contradict each other. So now he says he believes Sandy Hook happened as officially reported, but what's to say that next week he'll say he was coerced into saying that and he doesn't believe it really happened, then next time he's cornered he'll say he was tricked into saying he didn't believe it happened...
He's sort of like those cult leaders who make up stories to convince their followers, then come to believe those made up stories as real...except that where cult leaders are usually isolated from the outside world so don't get interrupted in that process, he's been interrupted in the middle of that changeover by the court proceedings. If you get what I mean.
