Someday there will be a question on the SAT’s asking:

Select the one that doesn’t belong:

1863 Lincoln issues Emancipation Proclamation
1949 Truman issues executive order integrating the military
1963 Johnson signs Voting Rights act
2004 Bush signs Fetal Protection Bill



But my real problems with this are:
1) It takes effect on conception not on fetal viability
2) It will probably lead to (imho) criminal penalties for smoking, drinking, etc while pregnant. Maybe even penalties for not providing adequate nutritional care.
