Abu Qatada.
We can't get rid of him, even though he (and his followers) would like to get rid of quite a few of us. We can't put him in jail and forget about him. We can't even send him somewhere 'safe', of his choice, so he takes us for mugs - and we are.
The media appears to treat him as some kind of celebrity.
Don't give him the oxygen, just ignore everything about him.
