In the post-survey, the last question seems best suited for an open-text: that is, the "are there any situations in which you would approve of a police officer striking an adult male citizen" seems to be more interesting if we ask participants to both answer yes or no, and provide an explanation of which situations, if yes, they imagine to be acceptable.
I agree that this question's binary response is imprecise, but I think we want to retain the response format to facilitate comparison to GSS responses.
