Didn't really expect that people would wanna apply ACAB to other countries. These two are definitely Public Safety though, and unlike their closest American equivalents, they don't make traffic stops or investigate serious crimes, so I highly doubt we're going to get any actual action with lives on the line.
While there is more I could say about the differences between the Japanese police we see here and American beat cops, I don't think any of it is really relevant to the story. I'm gonna sit back and relax while enjoying cute yuri hijinks.
