"In New Orleans is the "USA common law system" in force? Oh damn, feel almost useless.

Actually the 49 states, except Louisiana have the common law that is derived from England. Louisiana's system of law is derived from the French, whose law was derived
from the Romans. It is called the civil law.
As we are fond of saying here in Louisiana, the Romans had an advanced system of law when the barbarians in Britain were still throwing sticks and stones at each other. Obviously one system is superior to the other.
