Both the prosecutors and the defenses have an image of who they want as a jury, and neither get exactly what they want.
I found the voir dire the most interesting of the processes.
Sometimes you’re the wrong sex, wrong age, wrong color. And then sometimes, your profession is a problem/or/asset.
Often, as soon as I said I worked for a bank, any financial case I’d get tossed. Other times, when I answered that I was a business analyst… well, you don’t want anybody analyzing what happened… both prose and defense would stand and say “excused”. lol
