Krunoslav Borovec, Iva Balgač in Irena Cajner Mraovic v prispevku Police visibility as an influencing factor on citizens' perception of safety predstavljajo rezultate študije, v kateri so želeli ugotoviti, v kolikšni meri lahko taktike, ki temeljijo na vidnosti oz. prisotnosti policije, vplivajo na enega od pomembnih segmentov varnosti, torej na subjektivni občutek varnosti državljanov. V prispevku Preventing radicalisation and extremism Branko Lobnikar, Irena Cajner Mraovic in Kaja Prislan predstavljajo strategije za odvračanje posameznikov od radikalizacije ter predstavljajo rezultate študije vpliva usposabljanja policistov na krepitev zavedanja njihove soodvisnosti pri preprečevanju ali odvračanju od radikalizacije.
