If by police entrapment, you mean cases where, say, someone tries to put out a hit and doesn't realize that the person they're hiring is a cop, I think that's totally fair. That's still indicative of serious intent to commit murder, and it really is just luck that they happened to hire a cop to do it rather than running into someone actually willing to kill.
Same with the AM stuff, it doesn't really matter that my hypothetical SO was too dumb to notice they were talking to bots. Their intention was to cheat, and so the trust would be gone. At that point, how am I supposed to believe that they aren't cheating in other ways?
It brings to mind another thing that sometimes happens lately, where "prank" channels on YouTube or TikTok film themselves committing crimes, thinking that since they don't actually mean any harm, or say, are using fake weapons, it isn't a crime anymore. But, of course, it is a crime, the people who are being "pranked" in this manner believe they're actually in danger. There has even been a case where a prankster got shot for pulling a knife on someone as a "prank", and the shooter was found innocent because it was reasonable self defense.
