"Now, all of this raises important questions about what one means by "evidence,"or "medical information,"because the ultra-sound image is presented as a document testifying that the fetus is "alive," is "human like you or me,"and "senses pain.""The Silent Scream has been sharply confronted on this level by panels of opposing medical experts, New York Times editorials, and a Planned Parenthood film. These show, for example,that at twelve weeks the fetus has no cerebral cortex to receive pain impulses;that no "scream"is possible without air in the lungs;that fetal movements at this stage are reflexive and without purpose;that the image of rapid frantic movement was undoubtedly caused by speeding up the film (cameratricks);that the size of the image we see on the screen, along with the model that is continually displayed in front of the screen, is nearly twice the size of a normal twelve-week fetus, and so forth."
