If you are reading the jury instructions, a lot of the stuff here is reduce the appealable issues. In the olden days, before jury instructions were standarized, defense lawyers would appeal and say "the reasonable doubt standard given by the judge was unclear or misleading."
Standardizing a lot of this language prevents the judge from misspeaking and using the wrong term.
Judges have something to read.
@Teri_Kanefield what is the reasoning behind a jury not getting a printed version of the instructions?
Do you know how does requesting that the judge read them again work after the jury starts deliberations?
