fyi @ Common Law - Self DefenseSubmitted by donvino on Thu, 08/18/2011 - 23:48
Taken from a British Legal Book -
Principle - Quod necessitas cogit defendit
"...Any person has a right to use all nesessary force for the purpose of protecting his own person and the persons of those dependent upon him. He has a right to use force to resist force. It may well be that the defence of any one by any one is allowed. The term 'self-defence' is accordingly to narrow: and it is sometimes replaced by the term 'private defence.' We have said that the amount of force used must be reasonable; in other words, its is for the defender to maintain a sense of proportion." pg. 317
