There was a theory that roughly 15 years after Roe v Wade crime started decreasing because people who weren't ready for or didn't want children could now have an abortion. Many of those kids that were previously born "unwanted" were in poor households and so the kids getting to about 15 years old in those conditions would start getting into trouble and start committing crimes.

For any fuckwit that says "make better decisions then! Use protection!" I'm the result of a broken condom, that shit absolutely happens. I was a "pleasant surprise." Honestly I wish they'd have just had the abortion.
