I'm a well read technosexual who's bluntly honest about all things, although I try to be most honest about myself.
Police mostly refers to Prowl, who acts, yes, as a police officer for the Autobots, but also is a police car. (There are some moments with human police officers, and a bunch about spying and other governmental agencies meant to act in a protective manner, but they aren't really police forces. The difference becomes clear when Prowl patrols, because he's given specific orders, that are dealt with on the street, as a police officer, and not as spy or agent of any sort of acronymed agency.)
There are a couple issues: the man stirring up anti-alien fear, specifically against the Cybertronians, as well as the fact that Spike might not be as trustworthy as the Autobots once believed.
This was a far more compelling volume than I remember For All Mankind being, although I may go back and reread that before buying International Incident. (Which I want to read because of how Spike kills a Decepticon; it's brutal and I'm not quite sure how it was accomplished, so, yeah, there's that. I'll probably end up rereading this whole series in order at some point, too, and I own almost all the collections from sales.)
The spotlight with Prowl was especially poignant: he needed that hope, as much as everyone around him did. I do think it's not completely in character for him, but I enjoyed it despite that because of the feels.
