It was uneventful (a good thing), but they were professional when I was there.
There was no Republican Party functioning in our county so we only had a Democrat primary. My husband said he wasn't voting in another Democrat primary, so he ran for Republican Chairman and we started a party. Within four years, we had elected four Republicans to major offices. This Democrat district judge hated us for messing up her county, so she appointed a grand jury of people related to her or people working for a relative. She got a special prosecutor and his printed instructions were to look for Republican office holders committing a crime.
A friend of mine went to that grand jury and told the truth which was she knew nothing of any wrong doing by Republicans. The individual grand jurors could speak at any time and they said they didn't believe her, that she was lying. Within a week, she got another summons and the same thing happened - they called her a liar.
We decided if they called her again, to take the fifth. They did call her and she did take the fifth. The judge was furious and so was her grand jury but they had to dismiss her and they stopped calling her.
I knew they were looking for me and if they had found me, I also would have taken the fifth. There is no point in saying anything if they are just going to call you a liar and not believe you.
That whole experience and all those trials the Republicans had to go through, taught me that judges are just people and that's it. They will act for their own good and they don't care jack about the truth.
