From 51:25 in this BBC documentary [0] you're introduced to Horst Herold [1] the President of the BKA (Federal police) who instigated the creation of the Suchsystem Inpol sowie Analysen [2] to catch the Baader Meinhoff gang by trawling citizens data. Until the violence of the Baader Meinhoff gang, there was sufficient popular sentiment including in politics, against any Federal use of power as prohibited by the constitution. This was effectively reversed with the assassination of Alfred Herrhausen [3] using a enfilade of shaped charges to slice through his armoured limousine. Herold created the first European data dragnet to identify anyone who profiled similarly to his quarry. The gang were apprehended only using indirect evidence ,[edit: of their whereabouts]. Violence and the ensuing police reactions disheartened and suppressed opposition to Federal government enforcement.
