Genuine question, do you have a single source that suggests a causal link between Roe V Wade and crime stats? I ask because that seems like a pretty silly argument without evidence. Especially given the fact that the decades that followed Roe V Wade saw huge expansions in crime fighting organizations and laws that expanded many mandates for policing. Not only at the local level either. The ATF was only founded one year earlier and the DEA was founded that same year. The RICO act was only passed three years prior and wasn't being used to combat organized crime yet. At least not en masse. So please, cite some sources for the causal link between Roe V Wade and crime.
Okay so I just read your "citation" and I'm a bit confused. This isn't a study. Its not even really an informative article. Its opinion piece about a study that was done and it doesn't even break down the information in any meaningful way. There isn't much in the of reference to data in the study either. Half of it is about peoples reactions to the actual study Not sure why you bothered to link it. I pulled up the actual study and I gonna read that instead. Link if you want it: https://pricetheory.uchicago.edu/levitt/Papers/DonohueLevittTheImpactOfLegalized2001.pdf
This is gonna take me a bit to read since it has quite a bit of information in it. I'll get back to you when I'm done.
