In defence to chopjock though at no time did he say "he was there" or mention the words "calm sense". I think he was just speculating and it is being taken out of context
1) Talking is by definition a calm and deliberate action. Enraged shouting, which the eyewitnesses attest to, is not
2) His speculation is way off base, as the guilty verdict and sentencing today have demonstrated. This man was, the court found, irate and clearly not wanting to have a cosy little chat
