I wouldn't answer the kind of questions someone would likely ask if they wanted to know what my neighbor does for a living.

But either way there are several echelons of "undercover". Not every cop who is under cover is in deep covers for years on a RICO case.

And while it's unlikely they'd be wearing a body cam home, its more likely they might have a police issued taser stashed somewhere. Cops aren't smarter than your average individual and they absolutely will do things that aren't in keeping with SOP.

One of my friends works for a police department as a mechanic and their chief literally shot up her own police car by accident. Loaded service pistol in her purse. She was riffling through it and the gun went off (she claims). It's definitely not outside the realm of possibility especially if they didn't know.
