Your experience almost exactly mimics the one I had in the criminal trial I jurored for. I served as jury foreman, and without getting into specifics, I never once took a vote twice that had the same results both times. Everyone flip-flopped, everyone wanted to take a swaggering cop down a notch, no one believed in any of the evidence (and there was plenty), and all of them went on what "their gut" told them was "believable."
We deliberated for three days, and eventually agreed on a compromise because no one wanted to come back Monday. (It was a drug trial, and he was brought up on four counts. The compromise was everyone would vote guilty on the most serious of the four, and he'd walk on the other three. Talking with the bailiff after the trial, I came to find out that he was already in jail awaiting another drug trial while this one was going on. He had been released on bail three years earlier, skipped out, went back to dealing in the *same neighborhood* and it took the cops three years to find him, completely by coincidence, in a random corner stakeout.)
