The Early Jury
In the old days, juries were
pretty weird. Jury members were
neighbors of the parties to the case, and also witnesses, in a sense. The jury was sworn to tell the truth. If a defendant complained about the verdict,
a jury that was twice as big (the grand jury) was assembled to examine
the first jury. If the first jury was
found to be wrong by the second jury, the second jury’s verdict would hold and
the first jury would be punished!
We are asked to imagine how unlikely it is that the second jury would
actually elect to convict the first jury.
There were gradual changes in
this system. Witnesses could be called
who were not members of the jury to provide “expert” testimony. Eventually, slowly, the jurors were converted
into finders of fact who were supposed to base their decisions on the evidence
and not on their own knowledge.
