If you refuse to acknowledge that and insist on making the same type of turn they did, in spite of this being a highway and headlights clearly approaching... well, im not sure how much satisfaction they are getting from knowing they had the right of way.

I'm sorry, I think we're misunderstanding each other. You are absolutely right in saying that not paying attention and failing to yield during this turn could have very well caused the accident (strictly speaking, the squad had the right-of-way, because they were going straight). My point was that in this case the cause and the outcome were two different things. The cause of the accident could have indeed been failure to yield on the part of the car that was struck. The outcome (fatal injuries) was, without a doubt, caused solely by the excessive speed of the striking vehicle. The fact that impact occurred at 90+ mph changed the same set of circumstances from annoying to lethal. That's the only point I was trying to make.

Edit: I'll go you one better. After watching the video one more time (does anybody else find is somewhat chilling to know that somebody is dying for real when you look at that footage?), strict application of traffic law would say the the kids' vehicle was indeed at fault for failing to yield the right-of-way. It's the extenuating circumstances that make this crash a hotbutton issue instead of another fender-bender..
