I disagree with that POV. They are there in the context of a jury. They aren't at the grocery or the park as members of the general public, they are in a courtroom as members of a jury, sitting in a jury box. It doesn't matter that they were technically released, they had not been dismissed or allowed to leave. They had not been released from the building to enter the general public life out of sight.
No one said it was with evil purpose but I do believe it was unprofessional and inconsiderate, and if I were a juror I'd be upset. Me doing my civic duty does not include me being broadcast on national television, forever on the internet, associating me with a horrific crime, in an environment of corruption. Again if a juror comes forward, fine, but it needs to be their choice.
And I don't know how anyone didn't notice as the camera was close up of him walking past the jury.
