I recently picked up this phrase on a Netflix series and wonder what it means specifically. The situation was that a guy got information accidentally and was then chased by hostiles because he was aware of this information. The detective then said s.th. like "he probably turned a wrong rock"
.
I would assume that it means s.th. like
accidentally getting confidential information or information you shouldn't know of which brings you in a bad position
How would you describe it? And is there any similar phrase you could suggest to describe s.th. like this?
