I think, if an officer, does that to somebody, there should be a disciplinary action. Gallows humour is inappropriate outside the work, unless you know the person enjoys gallows humour himself. However, if he’s just speaking to other officers it should be considered private.
The officer that spoke to you was wrong, because it was your grandfather and he shouldn’t assume you can handle such a joke.
It was to dispatch but I could clearly hear it.
BTW Terre Haute Indiana , 1984. You never forget where you were when a grandfather dies.
Folks who work in morgues are the kings of gallows humor. Good thing nobody records the things they say.
