I've heard the phrase 'bin Laden' used so often on US news, that you'd almost think it is the correct way of addressing the one called Osama (use this name), son of Laden (don't use this name, duh).
That is, unless we're planning to address President Bush as 'the son of George'!
As someone who lives in a country with a growing Muslim population, and who has Muslim friends, I am perturbed at how little care has been taken to address 'outsiders' properly. This sort of ignorance certainly won't impress the rest of the world.
Even if Osama is the bad guy.
