Some are exposed to crime more often than others — repeat victimisation. A small group of offenders are responsible for a large proportion of all the offences committed. The same relationship is found in relation to the victims of crime; a small group of victims are exposed to crime repeatedly, and are therefore the victims of a large proportion of all the crime committed. Thus the colloquialism that lightning never strikes twice does not apply to the distribution of criminal victimisation. The repeated exposure to crime experienced by a small group of victims is found in relation to several different types of offence, including assault, robbery, car-related crime, and break-ins at schools and in shops.
