The reasoning behind you debate is
flawed. The most recent evidence
would suggest that Jack the Ripper
was in fact and American (showman I
think) who was resident in that
area of London over the period.
There was a Documentary on this
recently on a British tv channel
(can't remember which but think it
may have been BBC2), before the
police could question him he fled
the country and died before he
could be apprehended. There were
also 3 other main suspects.
The reports about it being a member
of the British Royal Family were
put about at the time to try to
soothe the public's anger at the
lack of police progress.
