I think stabbing a hooded intruder is a very reasonable course of action. Cameron needs to listen to the voice of ordinary citizens and change the wording to "use deadly force to defend themselves or their properties will not be prosecuted"
Anyway this incident happened in Manchester where the crazed judiciary dish out ASBO's to multi repeat offending street robbers so I'd expect the householder to get nothing less than a life sentence with a thirty year tariff
