I guess you misunderstood me.I can imagine it now. "Your honor, I defended my person and property in accordance with British Common Law as written in the year of our Lord 1492 and therefore I refuse to recognize the validity of these charges. I will be leaving now!" The judge responds "Yes, you will be leaving now. Bailiff!"
There is a great deal of precedent or case law on self defense. Not everything is in statute, and if you believe that statute is the be-all and end-all, then you are missing the point.
