There's a theory that the jury would have consisted of a high number of disabled and retired people, as they would be the ones least likely to have childcare or work commitments for a lengthy trial. This could explain the unusual amount of appointments, presumably for illnesses.
The only way this is acceptable in my mind is if a juror or their dependent has developed a serious illness during the trial. Otherwise, I think at this point they should be sequestered.
I know we say it is awful. But in some ways it is a privilege to live in a country where civilians can be to play a part in the justice system, especially enacting justice in the worst serial killer case we've seen in decades - either for the victims and their families (as we know and believe), or if there are any doubtful plebs on the jury, ensuring that the woman accused of said crimes gets a fair trial. Therefore, I no longer have any sympathy for whatever impact it has had on their lives: there is so much at stake here that they are responsible for.
