For various reasons, including fear, shame, and unwillingness to go through the ordeal of a trial, many victims do not report crimes. A 2006 survey found that only 32% of crimes became known to police, either through the statement of a victim or another person. Less serious offences, such as vehicle theft, were far more likely to be reported – probably because this is a condition of claiming insurance. More serious confrontational types of crime such as threats were less likely to be reported. While 36% of assaults were reported, only 9% of sexual offences became known to police.
