Each scientific or developmental project brings with it new challenges and risks, but also an opportunity to gain knowledge and development. The results of projects funded through national and international initiatives and programmes should be disseminated so that the experience and knowledge gained can be used in the future for the benefit of the police, academics and the public at large. It should be emphasized that the Polish Police is a uniformed formation dynamically developing new technologies for security. Project financing and management institutions, in particular the National Centre for Research and Development, play an important role in the indicated development, as well as in setting priorities and financing scientific research for security and defence. The 100th anniversary of Poland's regaining independence and the establishment of Poland's largest uniformed formation responsible for security and public order justify scientific exploration of the issue under discussion. The article discusses research activities in the police in three time frames: after 1919, after 1945, and after 1989 - the regaining of independence and sovereignty. The period of modern research activity in the Police was presented on the example of scientific activity of the Police Academy in Szczytno and the Central Forensic Laboratory of the Police. Good practices applied by the Police were indicated, i.e. the procedure for submitting by the Police projects in the area of state security and defence for financing within the National Centre for Research and Development funds. Moreover, the selected research projects of the Police implemented for the benefit of state security and defence were approximated. Apart from the indicated areas raised in the study, at the same time an attempt was made to answer the question whether the Polish Police makes use of the research experience of its predecessor (the State Police) in the field of creating technologies for security?
