You're just rambling. It's not our job to educate you on the facts of this case if you are too lazy to do it yourself.
I just saw some of sentencing on tv, Casey was in the partying mood, had her hair down and all.
Wow! You assume I didnt watch the trial? You assume I didnt read transcripts? Are you clairvoyant?
If you cant show from testimony whether it was an accident or if someone actually did something deliberate to take her life (i.e. murder) then you cant convict of one or the other. That was the dilemma the jury was in, thus the tears and angst expressed by jury members. The prosecution didnt pick which one to charge on. IMO they could have chosen either one to prosecute on and have gotten a conviction on at least negligent homicide but they didnt.
