"Murder by Injection" is a non-fiction book by Eustace Clarence Mullins, based on over forty years of investigative research. This work presents a profound analysis of the power structures that influence healthcare in the United States. Mullins examines the role of the American Medical Association and its impact on medical education as well as the control over the medical profession. The book highlights how these organizations and their practices affect the daily lives and health of citizens. It argues that doctors, despite their crucial role in healthcare, are under strict controls imposed not by state or federal authorities, but by private interest groups. These revelations provide a critical perspective on the interconnections between medicine, power, and their effects on society.
