Who is targeted by preventive repression and why? In the Soviet Union, the KGB applied a form of low-intensity preventive policing called profilaktika. Citizens found to be engaging in politically and socially disruptive misdemeanors were invited to discuss their behaviour and to receive a warning. Using novel data from Soviet-occupied Lithuania in the late 1950s and the 1970s, this talk explores the profile and behaviours of the citizens who became subjects of interest to the KGB.
