  It is well known that social media has revolutionized communication.
Nowadays, citizens, companies, and public institutions actively use social
media in order to express themselves better to the population they address.
This active use is also carried out by the gendarmerie and police organizations
to communicate with the public with the purpose of improving social relations.
However, it has been seen that the posts by the gendarmerie and police
organizations did not attract much attention from their target audience from
time to time, and it has been discovered that there was not enough research in
the literature on this issue. In this study, it was aimed to investigate the
use of social media by the gendarmerie and police organizations operating in
Turkey (Jandarma - Polis), Italy (Carabinieri - Polizia), France (Gendarmerie -
Police) and Spain (Guardia Civil - Polic\'ia), and the extent to which they can
be effective on the followers, by comparatively examining their activity on
twitter. According to the obtained results, it was found that Jandarma (Turkey)
has the highest power of influence in the twitter sample, and the findings were
comparatively presented in the study.
