Among the many other reasons we need to be grateful for our police force is the quality of the data they collect and keep. They are uniquely well placed to collate information concerning all types of criminal activity and, if we want to understand crime and how to prevent it, we must rely on their information, because criminals' own record-keeping is notoriously shoddy.
Researchers such as Jarrod Gilbert, author of the justly acclaimed Patched: The History of Gangs in New Zealand, depend on this material to do their work.
It is work which benefits us all. In Patched, for instance, he showed that much of what is commonly believed about gangs is incorrect. He is currently working on the subject of murder, also a topic about which many misconceptions abound.
So imagine his surprise when, on applying to obtain basic information, the police presented him with a contract to sign that would, among other things, require him to let them seek to "improve [his research's] outcomes" if, in Gilbert's words, "the results are deemed to be negative". They would also "retain the sole right to veto any findings from release". Any violation of this condition could result in blacklisting.
The usual chatterers will no doubt have been wringing their hands and claiming this means we live in a police state, but nothing could be further from the truth.
