I don't wish to disturb any ongoing arguments, but the first PJ CSI manual was only launched at the beginning of 2009.
Today, at the Polícia Judiciária’s School, in Lisbon, a crime scene practises manual is launched, establishing rules on how to enter, how to mark the investigators’ passage, how to photograph and/or draw a crime scene, among other procedures. “The potentialities in the collection of a certain type of residues are incommensurably different today from what they were years ago”, said Carlos Farinha, according to whom “nowadays the level of collection of elements on location is scarily superior”. Hence, he adds, the need to “reorganise and think about the manner to proceed on a crime scene”.

The launch of a manual is a step forward, but doesn't mean that the contents have been integrated into practice overnight. And that was for the PJ.
What was or is now available for the GNR or any other first responder at a potential crime scene?
What training or resources have been put in place?
