That's the bit I don't get..
Someone breaks into your home, threatens to "off" you with a weapon (of sorts) and, when you defend yourself, you get arrested and kept in custody...
Getting arrested, OK, the police have to "investigate" but, being denied your freedom by being held in custody when it is clear to all that you were the victim and, in the circumstances, only used what can be described as reasonable force to defend yourself is beyond me.
No doubt there will be a whole bunch of apologists and stacks of flowers left at the door etc because the scumbag who invaded someone else's property and threatened their life was a "good boy" really and a "pillar of the community".
I suppose that some would prefer that the police were looking for 2 burglars in connection with a murder
