As pointed out in Le Monde yesterday the problem is the independance of the state prosecutors and the police from political influence. Since it had been previously recommended by the Criminal Justice Commission in 1990 to revamp structure and procedure to effectively counter government meddling in criminal cases before abolishing the investigative magistracy, one has legitimate grounds to believe Sarkhozy is attacking the independance of the magistracy.
Never mind Italy where a two-tiered ancien régime judiciary system will soon gaurantee near total impunity to the elite and their allies. A far cry from "English-speaking" systems for whatever they're worth.
