'You have evidence to link non crime data to suppression of crime'
What crime? Exactly? Why is the suppression of that one area of crime considered of such importance?
Because tax payers want to know, why are the police wasting time on collating and using non crime data, not about burglary, or rape, or murder, or car theft, but about .... what crime exactly that they feel they have to deter? When there are woefully insufficient resources dealing with actual, evidenced, serious crime with very significant statistics.
