When is a bomber not a bomber?

When he's not actually bombed anyone or anything? And when he's only been charged but not convicted of terrorism-related offences?

I've been altered to a recent blog entry by the Conservative candidate for Bristol North West.
She says: "You probably, like me, gaped when you found out that First Bus has charged Avon and Somerset Police £125,000 - yes, £125 GRAND, for CCTV footage to help investigate the case of Andrew Ibrahim, the Bristol Bomber."

So much for Conservative support for civil liberties. Leaving aside whether he could, even if convicted, be accurately described as 'a bomber', whatever happened to the concept of innocent until proven guilty?
