Well, the widespread data retention in Europe is well-documented; most countries have even explicitly refused to comply with ECJ's decisions on the matter. To my understanding, geolocation data in particular is quite useful in investigations. Browsing and search histories and such frequently also appear in media pieces about convictions; he or she is said to have been interested in this or that. These cases certainly raise questions about the qualifications of such data as circumstantial evidence (unless someone is searching for guidance on how to build a bomb, etc.).
