> The 'Anglosaxon' term is a long-standing political science, history and diplomacy term. Its not something that can be ignored, especially because...
Well, being perhaps overly pedantic, but it should be written Anglo-Saxon, and there's a reason that it's hyphenated.
> The common law derives from the medieval !Anglosaxon! feudal law [...]
I have literally heard no one refer to it as "Anglo-Saxon" law before--it's "common law" or sometimes a formulation like "in the Anglosphere" or "English-derived law." Calling it Anglo-Saxon, in fact, would be wrong, because it's not Anglo-Saxon--it's Norman. (And, we're getting incredibly pedantic here, Anglo-Saxon rule was never feudal.) Even Wikipedia's page listing other terms for common law never suggests Anglo-Saxon, the closest being Anglo-American.
> The ENTIRE rest of the world uses the civil law system that descended from the Napoleonic law,
LOLNOPE. Actually, I think a majority of the world population might not even be on the civil law system (whether derived from Napoleonic code or not). There's a lot of Islamic law and customary law going on in several countries, especially several populous ones. Not to mention that many civil law countries never incorporated the Napoleonic code or any of its descendants.
> The persecution or the defendant can negotiate any outcome. This trait of the common law system causes all the parties to open the 'bargain' from the maximum bets that they can imagine, assuming that it will be 'negotiated down' eventually. Which obligates the need for lying and denying that was mentioned earlier - if you deny any kind of wrongdoing even when caught red handed, you have a better chance of negotiating something better than if you were honest.
Uh... I mean, by this point, it's pretty clear to me that you have at best a superficial understanding of how common law legal systems work, because this is confusing as heck, and it's muddled to the point that I'm not sure what you're trying to argue.
I think you're starting by talking about plea bargains, which is a concept that only exists for criminal prosecutions, and a quick perusal of Wikipedia suggests that some civil law countries do have facilities that are similar to plea bargains. But we're not talking about criminal prosecutions here, we're talking about civil disputes, and both civil and common law jurisdictions allow parties to settle out of court to resolve a dispute.
