Judicial oversight is not irreconcilable with confidentiality. It happens very often in large, complex investigations that search warrants are obtained and the “informations” to obtain those search warrants are sealed and will remain sealed for a lengthy period of time--until the investigation is complete, until all the arrests have been made, until all the suspected proceeds of crime have been seized, until all the relevant evidence has been collected. Simply resorting to the usual provisions of the Criminal Code in relation to sealing, in relation to judicial oversight of disclosure of that information--the editing of sensitive information so that it's not made public until such time as it's not going to compromise the investigation--is the scheme that, in our view, would properly balance the interests of law enforcement against the right of citizens to have their interests protected and to hold the state accountable for its conduct, ultimately.
