As a note, the DGSI is the result of the merger of the DST (counter espionage) and RG (domestic intelligence). The RG was a notoriously shaddy and scandals ridden operation, known for building files on French public figures (own file was typically the first document a newly promoted minister for interior requested to read) and was often compared to a political police. I wouldn't be surprised to learn that the officier in question came from the RG.
