“If the prosecutor wants an indictment, he’ll probably get one. The old saying goes a competent prosecutor can get a grand jury to indict a ham sandwich.”

Not really he can only give evidence...they are supposed to be independent thinkers

[dfwgator]

And they’ll be thinking to themselves, “Do I want to be responsible for a riot?”

...they are supposed to be independent thinkers Har-de har har to that. America is in very short supply for independent thinkers.

Some grand juries refuse to indict, but not many. The problem is there is no defense counsel allowed and even witnesses can't have counsel. There is no defense case put on - they only hear the prosecution's case. So, will this prosecutor present evidence favorable to the defense?

Also, it is not likely the officer will testify. His lawyer will advise him not to testify and it's almost unheard of at the grand jury stage.
