Did Matt Baker ask a 'killer question' on The One Show?

Oddly I was watching the end of The One Show last night so I saw Matt Baker's questions to the Prime Minister and I don't think his last question was a 'killer question' as many are claiming today. He asked how the Prime Minister slept at all at night. Many are saying that this was dagger alluding to how anyone who was implementing policies that were so heartless could sleep at night and that David Cameron looked shocked. When I watched the interview live it seemed that Matt Baker was wondering how anyone could get to sleep with so many problems and issues to worry about. Was I right or wrong? You decide...
