That's actually not the worst plan. If a politician is not prepared to answer uncomfortable questions, they should not then be given further airtime to answer only the ones they choose.
What irritates me most about a lot of interviewers is when they're presented with an outright lie and they simply move on to another pre-planned question without challenging the lie.
