Jack,
1. do you think it is easier to prove ones innocence, or do you think it is easier for the prosecution to prove a persons guilt.
2. it is generally accepted amongst the legal profession that to prove guilt in civil case, requires less evidence than is needed to prove guilt in a criminal case.
whether the french system has a better or worse record is irrelevant, what is happening in this case, is that because a family has political clout, they can cause an extraordinary circumstance, that is:the extradition of a person to another jurisdiction to be tried under a different system.
