Without speaking on any specific case, I have three detectives full-time who look after witness protection for the Toronto Police Service. They apply creativity in every single instance, and that creativity includes the issues we talk about: employability, location, other avenues and options to enhance the safety of the individual. It is not just about relocation and change of identity; it's a number of different factors that can create a safer environment for the witness.
As for testimony in camera, I can't comment on that. I'm not fully conversant with that issue.
