This is an excellent video produced in the 1980s by a former abortionist and founder of the National Abortion Rights Action League (NARAL).
Despite its title, The Silent Scream, the video is not sensationalist at all. It is very scientific. The doctor speaks as if he were teaching a classroom.
Starting at 7:00, he uses a plastic model to show, step by step, how a suction abortion is performed.
Starting at 12:45, he shows a real abortion as filmed through an ultrasound machine. It’s not bloody or gory, but still very thought-provoking.
Any pro-choice person should watch this video in its entirety.
