-70 • Aim at private interviews, especially on sensitive issues, and with persons in a situation of vulnerability; • Never discuss staff violence in group interviews; prevent detainees in talking about this in public; • During interviews, don’t ask about names and other details with no cogent reasons; • Avoid concrete recommendations to the staff concerning specific detainees after the visit; • Offer your address, phone number and other contacts to detainees who may be threatened. The safety concern does not end with the visit. After the visit, when preparing the report or recommendations, the monitoring team should consider carefully what details and names it includes within them, and should never do this unless it is safe for the detainees. When needed, it should carry out follow up visits to check safety concerns. Where the safety of a detainee is compromised, the NPM should never hesitate to complain officially.
