Some states in the world are perceived as having very violent policing; while others are considered repressive generally, but not necessarily via the police being violent .
I was wondering if there is some comparative data / indexation of police violence overall, or aspects of police violence, for many/most/all world states - something parallel to the "press freedom index" published by Rapporteurs Sans Frontières.
I suppose relevant aspects would be, for example:
- Killings by police per capita-annum.
- Detainments per capita-annum.
- Arrests per capita-annum.
- Police officers carrying firearms regularly per capita.
- Extent of use of riot control measures per capita-annum.
- Media-reported cases of police abuse per capita-annum in various categories.
and maybe other measures, or qualitative evaluations. Of course, some of the above might be problematic, in the sense that in a society with more crime, you may have more arrests without this being an indicator of police violence.
