Nigeria arrests fugitive ex-Liberian warlord Taylor

Maybe I'm in a weird mood this morning but how can someone be an ex-Liberian warlord? You can't be ex-Italian, you wither are or you aren't. And being a warlord is something that usually follows you around too. Can't be an ex-rapist or an ex-murderer. I'm just being picky this morning.
Former Liberian President Charles Taylor, on the run from war crimes charges, was arrested on Wednesday in northern Nigeria at the border with Cameroon, police said.

Now, you can be an ex-President. That makes sense. So why isn't he ex-Liberian President warlord? Is there no justice!

President Olusegun Obasanjo, currently on a visit to Washington which has been pressing for the former warlord to stand trial, ordered that he be immediately repatriated to Liberia, Information Minister Frank Nweke said.

Olusegun sounds like a futuristic laser weapon.
