I served on a jury, too, and didn't have a lengthy questionaire either. Both lawyers asked questions of the jurors like "Do you know the victim or the defendent?" An interesting note: On one case, the plantiff's lawyer was not very good, and it showed in the way he asked questions, especially comparing to the lawyer for the other side.
Do you know any of the following police officers? (insert long list) Do you know any of the witnesses? (insert long list)? The cases I heard were small. They just pointed around the room and asked generally, without a long list.
Do you the accused? Do you know the DA? The defense attorney? Did you hear anything about this case in the media? Does anyone in your family work for a police department? Do you have any biases? Do you have any prejudices?
What do you do for a living? They asked this differently. As I recall, I think it was more along the lines of if anyone was in law enforcement or a lawyer?
How long have you been working there. Did not ask.
Have you ever been convicted of a felony? As I recall, they did not ask.
Are you familiar with any of the following addresses? Did not ask
Would you be biased to tend to believe a police officer testimony over someone else? Did not ask. But then, no police office was involved with either case.
Would you be biased towards someone because of their race? Did not ask.
Since both the cases were the same type--one was a stalking and the other sexual harrassment, they asked if jurors had ever been sexually harrassed or knew anyone who had been, etc.
Professional profiling, itself, is not something they'll do for every case. This is likely going to be for a very high profile case with a team of lawyers. I imagine it would be for a celebrity case that gets a lot of press or a big lawsuit like a drug manufacturer being sued by a bunch of people for many deaths. Those people can afford to throw money at the lawyers, and if nothing else, profiling will be something that is extremely EXPENSIVE. Not every case would merit having profiling, and certainly, it would be out of the price range of many people. A lawyer is not going to use personal profiling unless there are really big stakes (i.e., major company will lose billions) because it is so cost-prohibitive.
But one thing I did learn, and this may be helpful ... every state is going to be different in what they do. In Los Angeles, we got horrendously long trials. It would take weeks or months just to pick the jury. A friend told me a story about the place where I live (and this is county-specific, by the way). A number of years ago a celebrity was arrested in our county and his lawyer showed up in court. The lawyer said that it would take two weeks to pick the jury, and another month to try the case. The judge told him he would take four hours to pick the jurors, and two days to try to case. Most cases here NEVER take more than four days. A rare one is two weeks. Yet, we all know about cases like the O.J. Simpson one that lasted for nine months.
You can generally visit the court and watch a case in progress unless the case is closed to the public. If possible, you should especially try to do this in the county of the place where your story is set.
