This is particular to Sweden. It is different from, for example, the Nepalese rapporteur. The Swedish government wants the national rapporteur to be situated at the national police for the particular reason that she would have insight into operational and intelligence work. Personally--and I think we both think this--it could have been better, in hindsight, to leave the rapporteur more independently outside the police force but with access, as she has, to confidential material and with the right to talk to whoever would be working in the office.
