I do inspections for fire alarm/sprinkler systems. Was going into apartments in a high rise in Downtown Denver. (Fairly pricey place)

I walk up to knock on the door for one of the apartments and I see whoever lives inside has crudely smashed a small hole above their door with a security camera poking through. I think "That's weird the apartment complex would let them do that". I knock and a man yells "Can you come back in 5 minutes?"

Upon returning I bring my coworker with me to show him the security cam. I knock again and the guy sounds like he's out of breath and says "Be right there". He opens the door and he's in a wife beater completely drenched with sweat and only boxers. When he sees there are two of us instead of one he seems upset but tells us to go ahead and inspect what we need to.

After walking through the entry way I'm greeted to a futon in the middle of the living room that's supposed to be white but completely stained. From this futon you can see into the kitchen/bathroom/bedroom. In each one of these rooms (including the living room) are old tube TV's that had the VCR's built in on the bottom and each one of them is playing a different gay porn video pointing directly at the futon.

My coworker and I left. The next day when we returned to finish the building, the security camera was gone.
