'Stranger' child-murder: issues relating to causes and controls.
Most industrialised countries are concerned with a perceived increase in the killing of children and adolescents by strangers. Though reliable statistics are lacking, the growth of serial murder suggests that more young persons may be at risk than ever before. Explanations, either of a psychological or sociological kind, of child murder by strangers are inadequately developed. Despite the tendency to see such killers as psychiatrically ill a number of studies suggest that the majority of offenders do not differ significantly, at least in psychological traits, from non-offenders. Subcultural and other sociological perspectives stressing "social disadvantage" have low levels of exploratory power and do not assist greatly in understanding child killings. Despite sketchy and contradictory evidence on the effects of the media on sexual and violent crime case study material supports the view that pornography, including popular music, may increase the propensity of individuals to commit atrocities. Counter-measures to control stranger child killing lie in more sophisticated law enforcement (profiling and computer links between police forces) long periods of incarceration of the offender and more sophisticated analyses of the crimes.
