I find it interesting that there are no more capital offences in Britain at all anymore, not even High Treason.

And I heard a story I'm not totally sure of:
The reason that in Britain water tanks are required to be on the top floor of houses is because when the Napoleonic War was being fought they were worried that old Nappy would sail up the Thames and start another Great Fire in London. So water tanks on the top floor so when he cannonaded the houses no fires would start.
