why is there a difference in figures from the police and the CSEW?
-police filtering info supplied to them by the public according to the factors that are important to them:
->seriousness (is crime trivial? eg littering
->classifying (how they categorise the crime)
->social status (may not view status of victim as high enough to pursue their case)
->discretion (chances of arrest lie within demeanour of person being challenged by an officer)-->Anderson et al. youths who cooperate & are polite to officers less likely to be arrested
