[Miss Marple]

Because he isn't running for office he has nothing to gain?

There are lots of things to be gained besides political office: positions on boards, speaking engagements, book contracts, and the ability to shoot arrows at officers whom you dislike.

I am not saying that any of these is his motive. He may, in fact, be sincere about his criticism. That does not make him correct, however.

[SUSSA]

Right you are. Nor does it make him wrong or suspect. His service coupled with the fact that he isn't seeking office should at least mean people consider what he says.

You are most reasonable in your reasoning.
