"We as an organization in general and our players in particular have to take into consideration our accountability to our fans in our decision-making. This was clearly a bad and unacceptable decision. We will be meeting with Shawne at some point to discuss this and pursue any disciplinary action we can take."The Pacers selected Williams with the 17th overall pick in the 2006 NBA draft.The Marion County prosecutor's office has asked a court for three days to file charges in the case.
