But all police organisations would have been in that position to begin with. It takes time to build up a database.
Quote from SIL blog (the news article was in the Portugal Resident a few years ago)
"A news report dated Nov 2009 said the database was completely empty, without a single entry, while the INML had received just 23 requests to provide matches.".
Additionally -
"Further, unlike the UK, it is not once on, always on. Criminal records in Portugal get expunged after specific periods of time, and whenever a criminal record was expunged, it was mandatory to remove the related DNA entry from the INML database.
By mid-Feb 2012, the national database stood at precisely 395 entries in total (criminal in the main, but also volunteer and civil). This was the date at which a major Portuguese news source reported the first successful use of the database in a criminal case. An offender was tracked via DNA in a theft case.
This case was then used by the police and related authorities to ‘advertise’ to judges the benefits of ordering DNA samples in cases of convictions for 3 years or more.
By the end of March 2015, the database had grown to 5,393 entries."
