The variance of the Gaussian you get isn’t arbitrary and related to the variance of variables being combined. So unless you expect people picking folks out of a lineup to be mostly noise-free, a very narrow Gaussian would imply a violation of assumptions of CLT.
This Jewish law thing is sort of an informal law version of how frequentist hypothesis testing works: assume everything is fine (null) and see how surprised we are. If very surprised, reject assumption that everything is fine.
having unanimous tesitimony means that the gaussian is too narrow to be the results of noisy testimonies. So either they gave absolutely accurate testimonies or they did something else than testify. Having them all agree raises more doubt on that everyone was trying to deliver justice than their ability to deliver it. If a jury answers a “guilty or not guilty” verdict with “banana” it sure ain’t a result of a valid justice process. Too certasin results are effectively as good as “banana” verdicts. If our assumtions about the process hold they should not happen.

Thus our knowledge on people being noisy means the mean is illdefined instead of inaccurate.
Sorry, what?
