Look - I repeat - the only way to prevent abortion is to prevent unwanted pregnancies . Just making it illegal never works. There were countless illegal abortions in America before Roe v Wade, and only an infinitesimally tiny fraction of them were criminally prosecuted .
There was no way to enforce the law and there won't be if it become illegal again . You can enforce laws against, murder, rape, physical assault etc . But laws against abortion are totally unenforceable. Even with all the advances in recent years in technology, there will be no way to enforce laws against abortion.
