In Italy it is usual for the prosecutor to open an investigation for manslaughter and aviation disaster...the rules goes in that direction to give the investigators all the power to inspect they need.
On there other hand we are talking about Roman Law Code merged with Cristian Church for whom misconduct, fraud and negligence are embedded in the human conduct and guiltiness must be fund.
P.S.: Sorry...just posted unaware of Sultan's answer.
