There's certainly jurisprudence by the Supreme Court on the notion of police independence, which defines the limits of political direction over the work of police forces. At the same time, I've suggested that there could be certain legal prescriptions on the police, for instance, through the Privacy Act. The Criminal Code, part VI, which has been referred to frequently, has transparency requirements that are imposed by law on the government and therefore include the police. You may want to have a look at these transparency requirements to see whether they should be improved. They're good, but they are probably perfectible.
