This is at least a well reasoned argument. One I wouldn't think is unreasonable. Employers fire people, team kick members off the team for conduct they may deem detrimental to their entity.I think the point is that a Grand Jury is composed of people with no relationship with whatsoever to any interested party in the case, therefore, the assumption, right or wrong, is that they are unbiased with respect to the case they are hearing. Employees of UK obviously have bias coming into the proceeding because UK is an interested party. They have a bias to protect UK's interest and not necessarily to protect the interests of either the accuser or the accused. The fact that they have a financial relationship with UK makes them a biased party to begin with.
However one might also argue that Grand Jury could well be bias in favor of a UK athletes. Given Tubman's height, perhaps some of the jury members thought he was a basketball player.
One more consideration is that the Board determined that Tubman had violated the Student Code of Conduct in a manner that would not meet the standard of rape yet still violated the code. The code specifies under the "Prohibited Conduct" section as being prohibited..."Sexual assault, stalking, and relationship violence, including threats thereof, as defined by Administrative Regulation R6:2 (Policy on Sexual Assault, Stalking, and Relationship Violence). ". Was there any history of relationship violence between the two? Had Tubman been stalking his ex? Perhaps this came out in the SRB.
None of us know. If you don't know then you can't assign blame.
