The fourth was a civil case. In California we only needed 9 of 12, and we had trouble getting the 9th juror the agree to guilt, but there is a lessor standard of proof and that can take longer to dig through.
I think you probably screwed up on the resisting arrest verdict. There is a very long history of cases that clearly state that resisting an unlawful arrest is a right.
Prosecutors often stack that charge on top of the others in order to increase their chances of getting at least one conviction.
