This subject was debated at lebth after the Tony Martin case. I emailed a point to BBCs Question Time programme. How can you use reasonable force against someone who is unreasonable by virtue of the fact that they've broken into your house and are probably threatening your family.

I, like most people would beat the **** out of anyone I caught in my house. If more burglars got beaten up or shot then it would be a bigger deterrent than the limp sentences handed out by judges.
I also believe that petty criminals would be less likely to re-offend if they were pilloried in public rather than be given a pathetic asbo or commmunity service order.
