There are at least four elements in play. 

She is the central figure in the situation, so naturally stories and posts focus on her and reactions to her actions. The one-to-many relationship in a small network/cohort is what makes it atypical and therefore noticeable (hestiant to use 'newsworthy', but it's along those lines of selling newspapers).  

The second element is rooted in sociocultural norms and expectations. These are far from universal, but it'd be disingenuous to suggest they don't exist. Why the double standard exists, its genesis and other factors are worth discussing, but not whether they exist. Those drove a lot of the framing of stories and responses. 

The third element, misogyny, plays a substantial (but not necessarily sole) role in leading to those norms and expectations, and drives a lot of commentary/reaction to it. Note that someone  can arguably harbor the mentioned sociocultural beliefs (which can be characterized as misogynistic) without necessarily being inherently misogynistic themselves. 

Lastly, the fourth element is that it's a high-profile profession with its own set of norms and expectations (both internal and external). If this were a group of dentists or accountants, the story likely would not have gotten much traction. But it's a group that is supposed to represent following and maintaining rules. Whether this was an internal gambling ring or some other coordinated ostensibly illicit (or at least promise-breaking) activity, that it was a group of police doing it draws attention. That this was an ostensibly lascivious activity increases this element.   

None of these are mutually exclusive and not all are necessarily present in each story/post.
