I seem to recall a discussion on PPRuNe a few months back reference a flight out of Miami or Orlando bound for the UK which experienced turbulence with consequential injuries to some passengers and crew a few hours after take off.
On that occasion, as now, a few people (who may not have been ideally qualified to pass judgement) whipped up a storm because the crew elected to continue to their destination. Eventually, wiser heads prevailed, and I think the defense they made of the crews judgement has some relevance in this case.
