Personally, I don't see much difference between being on-duty and off-duty.
But there is. When not at work you are in a different mindset. She didn't walk into the apartment with the mindset of being an officer on the job. When at home, I don't act the same way I do when on the job (such as language I use). Texting while on the job should be prohibited (because it's a distraction), but would you suggest the general public (which she is when off duty) should be prohibited to be texting while walking into an apartment, in case you walk into the wrong one?
If this was a police issued firearm, then that is an issue, and IMO police shouldn't be allowed to take them home with them.
