particular trend for each individual crime can be applied to the data,

Crimes of violence tend to be impulsive and therefore have lower

of how many will occur in a certain period (such as 5 years) or in terms
of full percentages, such as, ‘‘We can expect one rape in the next 15 years,
assuming no additional mitigation is introduced.’’
When analyzing rates,
