According to a Guardian article (September 2005), Scotland has the second highest murder rate in Western Europe with 2.33 deaths for every 100,000 people each year. Only Finland is more dangerous, with a slightly higher murder rate.
The murder rate in Glasgow, however, is almost double the Scotland average, with 5.5 victims per 100,000, which probably does make it the murder capital of Western Europe.
However, it is predictably much lower than the murder rate in low-income countries. According to WHO World Report on violence and health, the homicide rate in Albania, for example, was 21.0 (per 100,000 population), 21.6 in the Russian Federation, 14.8 in Estonia, etc.
