From the Executive Summary:
The main weakness of the package as a whole is that it does not remedy the lack of comprehensiveness of the EU data protection rules. It leaves many EU data protection instruments unaffected such as the data protection rules for the EU institutions and bodies, but also all specific instruments adopted in the area of police and judicial cooperation in criminal matters such as the Prüm Decision and the rules on Europol and Eurojust. Furthermore, the proposed instruments taken together do not fully address factual situations which fall under both policy areas, such as the use of PNR or telecommunication data for law enforcement purposes.
