I take it that's where the more upper class people that aren't rioting live? I'm an American, so I'm not all that aware of more intimate details of London's geography/demographics.
The West End is the dead centre of town - not much residential stuff there, but lots of big expensive shops.
It's a likely target - and there was some trouble on Sunday. London is easy to get around, and with kids hooked up on Blackberry, it's a valid worry that a 'flash mob' might appear in the West End.
Most of the trouble has been in further-out and poorer areas though - these have more residential properties and high streets where shops have been ransacked.
