If you’re going to try to write a high-minded moral tome, then at least give some lip service to the foundational principle of law, innocent until proven guilty.
Nobody yet knows what the arrested suspect actually did, or why he did it. Maybe he was confused, maybe he had a medical issue, maybe he was insane. A trial will explore all of these possibilities as well as the prosecution’s theory of the case, and perhaps the guy will “never see the light of day” but until that trial finishes, nobody should pass judgement. The videos are incomplete and in any case prove nothing directly.
