That would depend on what you mean

I doubt if there is a conscious effort on the part of the government to keep the people in ignorance of their nullification rights.

Yet the judges definitely see jury nullification as an abridgement of the judge's authority and power.
The judge sees himself as Big Boss in the courtroom, when actually he is there to see that the trial proceeds fairly. The jury is the real power in the courtroom.

The jury has the right to decide not only the facts but to decide if the law itself is just and is being applied in accordance with contemporary community standards.

If you have the chance to serve on a jury, simply pretend ignorance of the concept of jury nullification; you can nullify the proceedings AFTER you are selected to the jury.

You cannot make it null and void if you are not there! Remember this especially if a ped is on trial, or any other fellow travelers.
