Police in the Icelandic capital Reykjavik rarely need to use their weapons. But they do like to shoot pictures - for their hugely successful Instagram account.
The Reykjavik police initially set up an Instagram account to give the public a glimpse of their working lives - and went on to become an international phenomenon. In a city with a population of 120,000, not a single murder required a police investigation last year. According to 2015's criminal statistics, just 3,449 property crimes and 1,181 assaults occurred. So the cops have plenty of time to spend on social media!
