The difference between UK and US approaches is that UK law only  
applies extraterritorially to UK subjects or to persons "owing a duty  
to the crown". The latter has been used in cases where a foreign  
national is employed by the UK (e.g. a foreign spy employed overseas  
by the UK can commit treason against the crown). The US approach  
frequently claims extraterritorial jurisdiction over persons who are  
not US citizens and have no relationship to the US (e.g.  
"extraordinary rendition" under bounty-hunting laws or, as we would  
call it, criminal kidnapping).
