> nor is it required by all employers
Obviously lying isn’t required by all employers. Most employers aren’t the police (eg it is not the grocery clerk’s job to lie to you.) We are just talking about police, where lying to you is their job.
> Making it illegal for police to lie on the job would have the effect of many police no longer lying on the job, rather than putting all police in jail.
I still have no idea what you are talking about here. If you made something that the police do every day illegal then they wouldn’t arrest each other for doing it? That is obviously true but unrelated to the fact that it’s the police’s job to lie to you. Or it almost seems like you’re trying to say “if cops couldn’t lie to you then their job description would be different than it is now”, but that would just be another way of you saying that it is their job to lie to you?
I’m not sure what this fixation on hypothetical police that don’t lie to you is about, but again, saying “I am picturing imaginary police in my head where it’s not their job to lie to you” does not refute the fact that it’s the police’s job to lie to you, it affirms that it’s their job to lie to you. “All of my contrary evidence exists as stuff I made up in my head” is generally a supportive statement to any notion!
