I want to be fair and objective here, as Max's death also deserves thorough understanding. And if Max's death was not an accident, I'd like to know what exactly happened.
So what interests me the most about Dr. Bove's report are his following statements:
"In the absence of a mechanism to raise Maxfield Shacknai's center of gravity, no events or actions involving only Maxfield Shacknai and initiated at floor level, including those that involved riding the scooter, could be identified that were consistent with all aspects of the incidence scene and would result in an accidental fall to the first floor." (1st page of report)
"Other activities that would sufficiently raise his center of gravity so that it was higher than the railing, such as jumping, sitting on the railing, standing on a soccer ball or standing or riding on the dog must also be considered as potential contributing factors to an accidental fall, however, any these types of activities would have to also be associated with a sufficient horizontal speed and the proper trajectory to result in interaction with the chandelier. Any such alternative scenario would also have to account for the rest position of the scooter as discussed below. In other words, while a scenario such as standing on soccer ball is within the realm of possibility, one would have to be standing on the soccer ball while still traveling down the hallway with a forward horizontal velocity while also holding the scooter."(Page 18 of the report)
The first quoted paragraph suggests that Max could not have gone over the railing if he were initially standing at floor level.
I would ask what if Max first put the scooter on top of the bannister, perhaps still holding onto it or perhaps just resting it on top (a scooter is narrow and lightweight enough to sit on top of the railing without toppling over), then climbed atop it, and then rode the scooter down the railings? Standing on top of the railing would make Max was no longer merely standing on floor level, and that his fall could then occur, correct?
Or is Dr. Bove saying Max cannot climb atop the bannister? I find that hard to believe, particularly because according to Anne Bremner, one side of the railing was as low as 26 inches? That's a little more than 2 feet. And Max was what? close to 4 feet tall?
Also, there are nooks and crannies in the spindles of the bannister. Why can't Max put his feet in between the spindles to use them as a stepladder to get on top of the railing? I know I was a daredevil when I was young, and I'd put my feet anywhere that had any edge or gap to climb up! What's to prevent Max from doing the same?
Perhaps because the day before when Max was demonstrating riding the scooter on the carpet to Rebecca's sister XZ and he could only ride it slow due to carpet drag, Max decided to practice riding on the uncarpeted bannister so he could later show XZ when she came out of the showers? So Max placed the scooter on top of bannister railing. Then he climbs the spindle edges, gets on top of scooter and starts riding the scooter down the railings. Ocean the dog gets excited seeing Max atop the bannister, jumps at Max, knocking him over. Max screams out, "Ocean!" and manages to grab hold of the chandelier. Max's scooter falls first. The chandelier is swinging wildly with Max on it, banging Max against the different railings where he sustained his superficial back injuries. Then finally the chandelier gave way and Max falls next to an initially erect scooter, and the sudden motion causes the scooter to tip over and hit Max on his back or leg.
I'm not sure why the scooter was found on top of his leg. Wouldn't the logical thing be to quickly try to resuscitate Max and push every object away? Perhaps the scooter was on top of Max's back and Rebecca moved it but only slightly because she was too focused on giving CPR to Max?
From the second cited paragraph above, it appears that Dr. Bove also tried to account for the necessary rise in Max's center of gravity by suggesting that it is possible that Max was standing on the soccerball or the dog, except he says there still needs an impetus for the horizontal velocity. Well, what about after Max got on top of object to climb on bannister, Max rode on his scooter? The riding of the scooter on the bannister would account for horizontal velocity.
In summary, Dr. Bove did not make any definitive conclusions about the mechanisms behind Max's fall. He was however scientific in his assessments of what happened, but appears to have been limited in speaking out about additional scenarios besides the one accident scenario proposed by Dr. Gomez and the one homicide scenario by Dr. Melnick.
