The juror felt the killer “got away with murder” but said the jury was forced to render a not guilty verdict because the prosecution couldn’t prove its case.
They got it the wrong way round.
If the juror already felt a murder was committed, it is not up to the prosecution to give a slick presentation.
USA has such incompetent jurors.
Another juror was worse, she negotiated a book deal about the jury's role in the case, before the jury decision (guilty or not guilty) was made. Naturally the more controversial the decision, the more books will sell. There is a financial interest that undermines the juror's decision.
