Hors de combat. The Mc Naughton Rule

 Construed by jurists as the rules of criminal insanity,the Mc Naughton Rule more accurately,is,as in "Half-Hung Mc Naughton" of Co. Antrim repute,a mediaeval convention based on 'trial by fire',hors de combat and the latter is also known as "trial by combat".

The Rule?

"If you have survived death twice at the hands of any armed force in their respective jurisdiction,you will not be called on to serve again".

Not the Mc Naughton Rules of dolens incapax,rather the rule of brute force and ignorance.
