How the Nuremberg Trials operated:
In English law, the black cap was worn
by a judge when passing a sentence of
death.
I was reminded of this this
episode
[see clip at 16:00]
from the
classic 1989 British television
series Blackadder
Goes Forth whilst
reading the 1979 English translation
German historian Werner
Maser's 1977 Nuremberg:
Trial of the Victors:

John C. Woods at Nuremberg
As early as July 1946, 3 months
before sentences were handed down at
the main Nuremberg Trial, the
Americans knew they'd be executions.
Werner Maser wrote:
"Viktor Freiherr
von der Lippe
[...] one of the
defence
assistants in
Nuremberg, noted
in his diary on
12 July 1646:
'From a court
source . . . the
rumour went
round today
that,
irrespective of
the final pleas,
the Tribunal was
so far advanced
with its
findings that,
as things stood,
death sentences
must be reckoned
with except for
Schacht, Papen
and Fritzsche.
The hangman had
even been
designated
before the
defendants had
made their final
pleas. He was
John C. Woods,
who had executed
347 criminals by
hanging in the
United States
over a period of
fifteen years;
in August he was
given a secret
assignment
telling him that
he would shortly
have to go to
Nuremberg where
he would have to
execute the
German war
criminals."
