I understand. There actually is a well regarded study coming out of Stanford, and some other professor, that sugggested that the crime rate dropped first vis a vis the other states in the four states that legalized abortion pre Roe when the aborted fetuses would have otherwise hit the crime age, California (Reagan signed that law), New York, and two other states. That is the study so many of of the media picked up on years later. I posted the actual paper on this site years ago.
It's a more complex issue than most people believe it is. Tie both the crime rate and abortion to "immorality", because that's what both are, immoral acts.
