Eh, that would depend. If it were a new housemate and I suspected he was manufacturing and/or selling drugs on the premises,
I think I might snoop in order to have fair warning so I could kick him out before the cops burst in and arrested ME as an accomplice.
But that's not a likely scenario, since I live in a single-occupancy apartment. So, I dunno, if I had no reason to suspect illegal or
dangerous activities being carried out on my property, I would stay out of the room.
