The authors examine the characteristics of threatening and otherwise inappropriate communications sent to members of the U.S. Congress by a sample of 86 subjects, 20 of whom threatened assassination. We quote excerpts from these letters and provide quantitative data on such variables as the volume, duration, form, and appearance of such communications; the enclosures; the subjects' perceived relationships to the recipients; the thematic content of the communications; and the messages and threats communicated. Comparisons between 43 subjects who pursued encounters with members of Congress and 43 who did not revealed 17 factors associated with such pursuit. In this population, threateners were significantly less likely to pursue an encounter than inappropriate letter writers who did not threaten, regardless of the type of threat or the harm threatened. Inappropriate letters to members of Congress are compared with those directed to Hollywood celebrities. Mentally disordered persons writing to public figures often mention and sometimes threaten public figures other than those to whom the letters are addressed, which raises important issues regarding notification of endangered third parties and the sharing of information among protective agencies.
This is a descriptive study of 50 randomly selected male patients retained in a maximum-security state hospital for mentally disordered offenders. Data regarding the prevalence of several indicators of potential organic brain dysfunction are presented, including: (1) a diagnosis of any organic brain disorder, (2) a history of severe head injury with loss of consciousness, (3) a history of seizure activity, (4) evidence of cognitive impairment, (5) abnormal neurological findings, and (6) other relevant neurodiagnostic or historical findings. Results show that multiple indicators of potential brain dysfunction were present in 64% of the cases. At least one indicator of potential brain dysfunction was present for 84% of the subjects. Subjects with a diagnosis or history suggesting brain dysfunction were significantly more likely to have been indicted for violent criminal charges (p = 0.01). Implications of these findings for clinical treatment and forensic science decision-making are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
