Per the scientific journal PLoS ONE, pre-birth humans exhibit conscious "motor planning" and "social behavior" by "the 14th week of gestation." Likewise, the American Medical Association Complete Medical Encyclopedia states, "At 20 weeks ... the fetus now sleeps and wakes and hears sounds." More than 15,000 abortions are performed each year in the U.S. at 21 weeks or later, and the vast bulk of them are elective and not for medical reasons. Dismemberment is the most common type of late-term abortion procedure, and it involves pulling the limbs off unsedated humans. There are currently no federal laws against dismemberment abortions at any stage of pregnancy. Some states have enacted laws to prohibit this procedure after certain developmental milestones, but Democrats have promised to enact a federal law that overrules all of the state laws.
