I've heard about this one as well. It seems that the false report of the break-in was phoned in by a roommate who had become fed-up with coming home to scenes of sodomy in his living room, even if it was shared. If they'd just restricted their perverted activities to their own bedroom (ie if they'd kept it private) then this wouldn't have happened.
By the way, the roommate was charged with filing a false police report but I can't remember how that played out. I think he got a fine but I'm not sure.
Anyway, as I said, this never happens where there's a reasonable expectation of privacy.
The news story says the men were arrested in the apartment of one of the men. Despite how you say "it seems", the article says nothing about a "roommate." It says nothing about sex in the "living room." And I'll bet you can't find anything to support those allegations. I see nothing that indicates these men did not have a reasonable expectation of privacy -- yet they were arrested, nevertheless.
