Sometimes you have to read between a line or two and correlate what you are reading with known facts. Oh and you might recall that OBL has declared jihad on all infidels both in the ME and abroad but in the ME its a major "abomination", "heresy", etc.
BTW unless you're with 'ol OBL you're an infidel (not a good thing). Cheerio!
You can stick your crayons back in the orifice from which you got'em. In two tries, you haven't referenced anything regarding "Britons left in jails".
The text of an article should support any charge made in the headline, not just present a scenario where the charge is possible. The Guardian could re-title it 100 things that are possible, all of which would be just as supported as this one. If you can't see that, crayons are just about right for you.
