The operative word in that sentence is MAY it is a shame that many here, and apparently yourself, have turned that "MAY" into DID.... When there is nothing of factual basis to even support the parents even are swingers in the first place, much less that if they are that it contributed to their child's disappearance. Those of us who understand the meaning of the word MAY and MIGHT do not jump to conclusions by assuming they mean "DID".
If these parents DID place their children at risk, I will condemn them for it. But I am not going to do so based on some talk show host and internet prattle.
