Warrents and police investigations in the workplace .

So we recently had a cop asking us for some information. Am I reasonable to ask for a warrent even if my bosses did not?

The way I see it, I don't know if the cop is doing a real investigation or if I am becoming an accomplice to them abusing their power and stalking their ex or someting. But am I actually empowered to ask?
