Obviously. No matter who you invite into your home, if you have little ones, it's your responsibility to question why they are going into your childrens' bedrooms. Especially people you meet and bring home from a bar at 3am for a little "party".
Obviously these people have no sense. They could just as easily had their orgies away from their kids, they have cheap motels everywhere for that kind of thing and then only the parents would be exposed to a sex killer. I don't really care what they were doing, they've lost a child which should be punishment enough but they also apparently weren't exactly upfront with the police in the beginning even to help find their daughter and instead made up stories about doors being left unlocked. It was like they wanted to protect their orgy friends more than find their kid.
Please provide your source for this information. Who went into Danielle's bedroom, who was present at this "orgy", how many people where there.
You seem to have some pretty intimate knowledge of what went on in that house in the middle of the night.
Or are you now just making stuff up out of whole cloth?
That seems to be the case here.
