Ross Kemp on GangsHighest murder rate in the world for a country not officially at war. Ross visits Kingston, the most violent area in all of Jamaica, and speaks to gang members there.

A study carried out by A. Harriott shows that the homicide rate in Jamaica is four times higher than the world rate, with the city of Kingston having the highest rate in the world at 109/100,000, followed by Washington D. More.C., at 67/100,000. According to this researcher, there is a direct relationship between the rate of murder and the rates of other violent crimes-robberies, rapes, etc. In Jamaica, historically, most murders were crimes of passion.

In 1963, in 64% of the murder cases, the victims were known to the offender, and domestic violence accounted for 28% of all homicides, while in 1993, this declined to 16%. This does not mean that cases of domestic violence are on the decline, it means that the murder rate – especially since the increase in the number of illegal guns on the island – is going up.

Ross uncovers the extent to which the Nazi, or National Socialist, groups are gaining power in Russia: it would seem that at best the police turn a blind eye to racism, at worse actively endorse it. And Ross meets one Member of Parliament who openly promotes Nazi ideology. Ross joins one Neo Nazi group during their training and through a series of tests -which include him being set on fire – he gains their trust. They invite him back to their secret headquarters where he meets some seriously disturbing individuals and uncovers the heart of their violent organization.

Orange Country, California, regarded as the birthplace of American skinheads. The recent amalgamation of various factions has led to the creation of the Orange County Skinheads where Ross gets to grips with the impact of this group on a concerned community.

In Poland, he follows Neo-Nazi football hooligans who have become one of the most feared gangs in Europe. Young men with few prospects use violence as a means of escape, and Ross experiences first hand just how dangerous it can be when he's tear-gassed at a football match.
