In going through materials related to a client, a claim was made that a victim never used their right hand. Video was shown of the victim bowling with a house ball using their right hand. The "smoking gun" given by the prosecution to refute that and claim it as an isolated occurrence was that "house balls are only drilled to fit the right hand."
I'm sure there is something I could find by spending more time on the web looking for the answer, but I have some qualms with the claim advanced by the prosecution. Simply put, my recollection of most generic house balls (not including ones donated or abandoned by bowlers) is that they have spans and pitches that were very average and not geared to one hand or the other. Hence, you could grab a house ball of the appropriate weight and throw with either hand (depending on whether said bowler was right handed or left handed).
Can any proprietors, ball reps or drillers offer some insight? I know it is the weekend, but I really sort of need an answer by Monday AM. There are other issues present in the case that have far greater significance than this question, but reading it in the record just made me want to call BS.
