This Amnesty International report is much clearer:
...the lack of the crime of torture in the Italian criminal code has prevented judges from punishing perpetrators in a manner proportionate to the gravity of the conduct attributed to them.I believe that this is another indication that capitalist ruling classes across the Western world are headed toward more overt police state methods of controlling descent. This incident also exemplifies how ruling classes suppress information until it no longer poses much of a threat to their governments.
The lesser crimes are by now subject to statute of limitations, which means that no one will serve any time in prison.
Furthermore, systemic failures which contributed to the violations in Bolzaneto have not been addressed by the Italian authorities. Amnesty International said it is concerned that the Italian authorities have failed in the past nine years to take any measure to prevent police brutality of the scale occurred in Genoa in 2001 from happening again.
