In the section on Thomas Jefferson, an editor asserts that abortion was legal prior to 20 weeks in Jefferson's time. I believe he has badly misread the two sources he uses. The first source, Blackstone's, states that abortion or killing a child in utero after 20 weeks is considered manslaughter homicide, but prior to 20 weeks it is a less serious infraction, perhaps a misdemeanor (still a crime). The second source makes no assertions whatsoever about the legality of abortion but rather reaffirms life. Both these sources are legal commentary, not law. I would like this parenthetical section removed if proper substantiation for its assertion cannot be found.
