Daniel Drezner has been watching the coverage of the current show trials in Iran, and points out that they are not working very well in cowing the population, and suggests that in the television age show trials do not work, as it is harder to control the images that people get of the trials. He asks "can show trials ever cement an authoritarian government's legitimacy?" In comments someone suggests the trials of the Gang of Four, which I think is an interesting idea. The trials of the Gang of Four were seen on film by Chinese people, although not on television by most I would assume. I think the real difference is that the medium is not really the message here. Stalin, I believe, did not broadcast his entire show trials on radio, but rather news items about them (or so I assume). Likewise Chinese people (I assume) saw the trials as heavily edited newsreels. The trials themselves did run off track a bit, most famously when Jiang Qing, who was being accused of plotting the Cultural Revolution without Mao's knowledge said that she was "Chairman Mao's dog, whoever he said to bite I bit." (我是主席的一条狗，主席要我咬谁就咬谁) Chinese people, of course, did not hear this. I don't think the problem is so much video vs. audio but the sheer bulk of what you want to show people. A trial is a major thing with hours and hours of testimony. Stage managing a huge reality show like that is hard, particularly when you are not trying to generate sympathy for the accused, given that the trial itself is set up to make the accuesed look helpless before the power of the state. Even more important than medium, however, is context. I assume Stalin's show trials were effective in convincing people that they really, really did not what to get on Stalin's bad side, but they were only one of many things that did this. The trials of the Gang of Four were intended (I think) to convince Chinese people that the CR was really over and to shift blame from Mao and the CCP as a whole to the safely dead or imprisioned. They did this, but the trials, which started in 1980, were the end rather than the beginning of this effort.

I don't think show trials alone can do that, but they are a useful part of authoritarian political theater if used properly.
