that isn’t just Florida. It came about because of the difficulty of getting enough jury members to serve. Apparently for this case they needed to have a pool of at least 300 people to pull from. In order to actually get 300 people to respond, they had to call 600. Sounds to me like something is definitely wrong with our legal system that people can so blatantly (and apparently without penalty) ignore a jury summons.
I would be happy to serve on one and in my 73 years have only been called once but wasn’t even selected to be questioned. I don’t know why people are always so anxious to get out of it.
