Yes, grand jury proceedings should be secret. Those on the grand jury have the power not the D.A. If only they realized just HOW MUCH power they have ...

It is often said that “knowledge is power”, but how much power do they really have if a prosecuting attorney has discretion over which evidence is presented, no judge is present, no counter argument person is present, and the PA has strong control over the room?
Only situation involving drug informants and the like should go to grand juries. The rest - either take it directly to trial or don’t.
