Ex-attorney: Bill Cosby cannot be prosecuted

The former district attorney who declined a decade ago to bring sex-crime charges against Bill Cosby has testified that he believes his decision is binding on his successors and forever closes the door on prosecuting the comedian.

Former Montgomery County District Attorney Bruce Castor took the stand as part of a bid by Cosby’s lawyers to get the case thrown out because of what they said was a decade-old non-prosecution agreement from Mr Castor.

The current district attorney has said there is no record of any such agreement.
