oh my god I'm so angry at the authors of this study.
This study finds that the passage of such laws is not related to the number or frequency of criminal incidents in these spaces.
THEY DIDN'T FIND THAT.
Their NULL HYPOTHESIS was that there was no relationship. They failed to reject their null hypothesis. This is like the most basic thing they teach in statistics! Failing to reject the null is not the same thing as accepting the null.
I'm actually raging that they could report it this way. It's wrong.
Look at the confidence intervals on all their results! They should be saying "well, we went to a lot of effort to gather this data but in the end it wasn't good enough to tell us anything." But no, they're saying "well, we couldn't find anything, therefore there's nothing to find." YOU CAN'T DO THAT. You sloppy bastards. Or maybe they're just agenda-driven bastards.
The Boston Globe is even worse in how it reports it. "Study finds no link...no relation... no increase in crime" No, it should be "Study doesn't find a link" They absolutely didn't find that there is no link!

I don't know whether I'm more infuriated by this failure of basic statistical reasoning or by people leveraging the statistics fail into propaganda that makes women unsafe. (See the Target study, and the Times FOIA request re unisex changing rooms, which both constitute pretty good evidence that the threat is real.) I mean, okay, it's the latter but they're both maddening.
