I can't hardly imagine that most people posting here would ever consider a job where literally every word or sound that came out of their mouth during their entire working life was recorded, and likely subject to public disclosure. Saying that this is what cops signed up for is not a compelling counter argument either, as this is new and most of the cops in question didn't sign up to work in an environment like that at all.
It seems odd to be even somewhat defending Chicago cops but someone should point out that there are two sides to this.
