The mills of French judicial enquiries (not necessarily criminal) tend to grind extremely slowly".
It's all well and good to say that but when it comes to retrieving data it should be done as expeditiously as possible. If a system, like this French criminal investigation one, slows that process up, then we should demand that the system is changed. I know that is a bit idealistic but as confiture said
if tomorrow morning, a NWA 320 crash out of Minneapolis ... ?
then we would all be crying out how silly it was to let the system muck around with such valuable information. To delay the extraction of potentially life saving data is bordering on criminal itself.
