Excellent. I think the most important rule, never to be broken, is that all interrogations must be videotaped. It protects both those being interviewed/interrogated and the police.
I also think that Italy's system of having the prosecutor lead and direct the police investigation is highly flawed. Prosecutors are looking for evidence of guilt, not innocence. It is inherent in the prosecution mentality. Mignini, by his own admission, saw Amanda and Raff guilty from the very beginning. The police should be independent of the prosecution, control the investigation, and then report their findings to the prosecution.
Having a prosecutor leading the investigation can create disastrous consequences when you have corrupt prosecutors such as Mignini running investigations.
