the flaw of algorithm is that they quite logically produce a good quantity of apparently illogical / unpredictable / seemingly false results. This if they work in perfect environment, what they never do : other algorithm crash the system, hardware can be defective...

The best way to feel it is the game "Lemming" : you have to lead a colony of lemmings from point A to point B with a defined set of instructions, and few obstacles, and invariably drop a good share of them in the sea trying.

As a cartesian french (but perhaps not a representative one) I would not rely too much on law, algorithmic or not. I would :
- take into account the possibility of a deffective piece in he system : for example an over-indulging prevost ("that guy attacked first"), or no prevost at all (sick, far, sleeping, drunk...)
- have in mind that the legal frame will interact with the doing of the criminal (if not too drunk) : why not to call help from the soldier's mates against a spanish aggression, or to threat his family into silent, etc... ?

Sincerely,

Jean
