Way back, I remember seeing a revised model of the way information about a current investigation might be imparted into the wider domain and I recall being struck that it seemed to mirror the way information about UK investigations is released, with laws very similar to our own sub juducie laws, and a definite relaxation on the (official!) position of absolutely zero information being released.
My impression is that Portugal is moving forward at an accelerated rate, but change takes time and resources.
The previous blanket judicial secrecy was an open invitation for a potentially corrupt relationship between the PJ and the media. As we know, there are scandals over such corruption in probably every country, but the absence of a police media relations service can only make it more endemic, IMO.
As a PT newspaper editor once said: "Judicial secrecy is like traffic regulations. Everyone knows they exist, but no one takes any notice."
Establishing a win-win functional service required rethinking the laws. If the laws have been revised, then that may pave the way, but establishing one will presumably require more resources - including a clear strategy (which itself would presumably involve change management).
