Bill Cosby, under fire for sexual assaults claims from multiple women, attended his first hearing in Norristown, Pa., Tuesday, and former Montgomery County District Attorney Bruce Castor, considered a key witness by Cosby's defense team, refused to file charges against Cosby in the current defendant's previous case, citing "insufficient, credible and admissible evidence." However, Castor points out that he is no ally of Cosby and hopes the prosecution succeeds.

"Let's be clear, I'm not on your team here. I want (the prosecutors) to win. What I think is that Andrea Constand was inappropriately touched by Mr. Cosby, I am not analyzing back in 2005 as to what I think. I am analyzing it back in 2005 as to what I can prove," Castor said, according to USA Today.

In December of last year, authorities arrested and charged Cosby with drugging and sexually assaulting Constand, a former Temple University athletic department employee, in 2004.

During the 2005 trial, Castor refused to charge Cosby due to lack of evidence but intended for Constand to receive monetary compensation since he believed her story.

"I thought making Mr. Cosby pay money was the best I was going to be able to set the stage for. I was hopeful that I had made Ms. Constand a millionaire," he said.

Castor told Walter Phillips, Cosby's lawyer at the time who has since died, that Cosby would not be charged as long as he testified. The documents containing Cosby's testimony were unsealed last summer and are damning evidence in this new case, as reported by the Daily Mail.

Cosby is also required to attend a second deposition in Los Angeles. Judge Craig D. Karlan ordered Cosby to answer questions regarding a woman who claims Cosby abused her in the 1970s when she was 15 years old, according to ABC News.
