Crossfire, a companion to Citizens' Forum, was a series of four discussion broadcasts. The programs alternated between two different formats. In one, an assembled panel of experts opened itself to questions on different subjects by a studio audience. In the other, a form of debate, each side of a question had two supporters, one a "witness," the other a "cross-examiner." After the cases for both sides were presented, a chairman provided a summary and invited the audience to judge the merits of the arguments and decide the winner.
