"I AM NOT A SCIENTIST"

When some politicians are asked a question about, for instance, global warning, they answer: "I am not a scientist". This can have either of two meanings, and the speaker should specify which he means. (A) I am not a scientist, so I listen carefully to what science tells us, and act in accordance with it. (B). I am not a scientist, so I feel no responsibility to be guided by what science tells us. Anyway, "scientists" seem to be mainly trying to destroy the economy and reduce business profits.
