Turnbull explains it all
That man was the reason I became a Mountie; he was in a recruitment video that they showed for years. Really, I think they filmed it in ’81 or so and careers officers just kept playing it. At the end of Depot, he returned to his home community as he’d always intended. He didn’t join the RCMP for its own sake; he joined because he wanted to protect his community and help the people he loved and protect them from crime and exploitation.
