Three political scientists diagnose the current state of political influence on jury selection in political trials, based upon personal experience, upon the literature of political theory, justice, and law, and upon recent action of lawyers, judges, defense committees, and some defendants. Political trials are interpreted as formal examinations of persons who have threatened governmental authority. Trials of Huey Newton, Angela Davis, the Chicago 8 and Dr. Spock are noted as examples. The paper considers five major topics: (1) the relationship between political action and political knowledge; (2) constitutional and legal procedures of jury selection from composition of the jury pool to selection of particular juries; (3) the social science techniques utilized in jury selection; (4) the politics of jury selection; and (5) designation of areas related to the jury selection process in which political action could be initiated and encouraged. The authors recommend that activists consider the potential for political action during political trials. The conclusion is that political scientists should give serious philosophical and empirical attention to political trials, should reflect on the possibilities for political action through involvement in such trials, and should absorb into political science the concomitant development of knowledge about this area where politics and justice mix.
