Answer 7

Someone had to be there to hit the Stop and Rewind button in order for it to be all ready for the detective to listen to when he walked in.

(I answered that all by myself, I didn't read the other people's answers before I figured it out for myself.)

Answer 8

He didn't have to rewind the tape. If it was suicide, the tape recorder would have still been on or it would have been at the end of the tape. Because he only had to push the play button, someone else had set up the tape for him.
