Suppose we have 100 people, 90 white, 10 black, and the following stats: 5 blacks commit crime 4 are arrested black arrest rate is 80% of black crimes, 40% of black population "true" black crime rate is 50% of black population, 5% of total population police search 50% of black motorists without cause
50 whites commit crime 20 are arrested white arrest rate is 40% of white crimes, 22% of white population "true", white crime rate is 55% of white population, 50% of total population police search 10% of white motorists without cause How do I find these numbers? Is it possible to know the "true" crime rate? I'm assuming violent crimes, or perhaps "street" crimes. Are there figures that measure the above for street crimes, white collar crimes, drug crimes? How much of reported crime (I'm assuming arrest rates are the conventional measure?) by blacks and whites is a result of differential attention paid to these two groups by law enforcement? How have laws changed to perhaps direct law enforcement to treat the groups differently? Bill
