We've always had to provide an account of our actions. What this is saying is that you must provide a statement now. It says you will sit down with me, I'm going to interview you, and you're going to provide that statement.
An account of my action is, “ I got on duty; I went to the scene; this is what happened; here are all my notes; here's my report, and this is my action. If you have some more questions, here's my lawyer, we'll answer those questions for you”, and there you go.
You're right that they're the same protections a citizen has. If you commit a murder, I will ask you questions, but you have that right not to talk and you have a right to speak to a lawyer, and if you can't afford a lawyer, a lawyer will be paid for.
As we've seen in the RCMP, the commissioner will review every time you're under investigation and he may withdraw that support. He may withdraw that legal funding for your lawyer to protect you under certain self-incriminating investigations.
