For me, it all comes down to the hardest of the hard facts. There is a dead body in the snow. It belongs to John O'Keefe, who exited Karen Read's car just a few feet away. After exiting the car, KR does a reverse turn at about 24 mph and, probably accidentally, hits JOK. The evidence? JOK's dead body is in the snow. There is no hard evidence JOK ever went into the house. There is no hard evidence that someone in the house murdered JOK. As far as I know, there are no drag marks or footprints in the snow indicating the placement of a body there. All the other testimony, such as about broken tail lights and such, is distracting from the hard facts. Those for and against "guilty or not guilty" can cherry-pick testimony that "proves" their point. I don't know why JOK had cuts on his arm. I don't know why the residents of the house didn't wake up when all the activity was going on later. I don't know where and how the tail light was broken. It doesn't change the fact that JOK's body is lying a few feet away from where KR dropped him off.
I believe that there was no conspiracy among the folks in the house. I probably wouldn't like those people if I knew them. I abhor their drinking culture. I know that culture very well having lived in similar communities. Unfortunately, JOK was part of that culture. I don't think I would have liked him either. He should have known better than to let a very drunk KR drive. If one of the "McAlbert" crowd did kill JOK, there is no way all the others in the house conspired to blame it on KR. They couldn't keep that secret because they are such heavy drinkers it would come out eventually. Alcohol is like a truth serum. They believe KR hit JOK because he is dead on the lawn and they know that no one in the house did it. Therefore, they cooperated in getting the actual facts straight because they wanted justice for JOK. Cooperating on getting the actual facts straight is not a conspiracy to cover up a murder.
KR will probably get acquitted or maybe there will be mistrial. There were too many paid experts on both sides, which created a lot of noise and distracted from the hardest of the hard facts: that JOK's dead body is on the lawn after exiting KR's car just a few feet away from where a very drunk and angry KR then reversed the car, probably accidentally hit him, and drove away in a huff. But she couldn't escape the thought during moments of lucidity that she may have hit him, and that dictated her actions through the wee hours to come. If she is acquitted, I hope his loved ones find some solace in that she has spent the last three years in a punishing purgatory.
IMO.
