Cops suck everywhere all the time always.
Of course, this part is a given, it's in the very nature of their institution - but the exact level of danger faced by a trans woman in such encounters will probably be quite different from one jurisdiction to another.
Decades ago post-op trans women were 100% safe: in 1980s, 1990s etc if you had female genitalia between your legs, no one would ever stuff you into a men's jail or prison. It didn't matter if those female parts were there from birth or if they were constructed in surgery - female parts between legs meant women's jail or prison. You were likewise guaranteed female ID documents if you were post-op. But today's evildoers have scooped to lows that never previously existed in all of human history, treating post-op trans women as male and stuffing 100% anatomical females into men's institutions.
I am a post-op trans woman. I got my SRS primarily in the hope that it would make me safe - but now it is still not enough. Hence I am asking how it is in Oregon: are they Trump-level evil too, to the point that they would stuff an anatomically female person with men because her female parts weren't there from birth? Some of the wording in your original post kind of points in this direction - when you say they asked you "What genital were you born with?", questions about surgeries and "Safe around other men or no?", it sounds like you got woman parts, but the evil pigs were still looking to stuff you with men because those parts weren't birth-made - unless I totally misunderstood your meaning and intent in those passages, in which case I apologize in advance. But being a post-op woman myself, now I am understandably worried if I would be in danger of treated like a man or stuffed with men in Oregon if some unfortunate encounter with state-sponsored terrorists goes the wrong way.
AGAB or genital anatomy? Has there ever been a test case to distinguish between the two? I.e., a case involving very specifically a post-op person who underwent an old-fashioned, 1970s-style 100% sex change?
