Evaluate the top down approach. (DISADVANTAGES)
1) Top-down profiling only applies to certain crimes (e.g. rape, arson, cult killings, and murders that involve macabre practices such as sadistic torture, dissection etc.). Common offences, such as burglary do not lend themselves to top-down profiling because the crime scene reveals very little about the offender.
2) The organised or disorganised distinction was developed based on interviews with 36 serial killers in the USA. Critics have pointed out that this is too small and unrepresentative a sample upon which to base a typology system.
3) The organised or disorganised distinction is overly simplistic. Holmes (1989) suggests there are four types of serial killer; visionary serial killer (kill because God or the Devil is directing them to), mission serial killer (kill to eradicate a group of people they consider to be undesirable), hedonistic serial killer (kill for the thrill) and power serial killer (kill to have complete control over the victims).
4) Canter et al. (2004) analysed data from 100 murders in the USA with reference to the characteristics thought to be typical of organised and disorganised killers. The findings did suggest evidence of a distinct organised type, however this was not the case for disorganised type which undermines the entire classification system.
