Absolutely. I actually went to trial many years ago because a DA wouldn't back down, he thought I'd bend. I didn't. We literally had video footage of the culprit, it clearly wasn't me and clearly WAS someone else. The DA waited until the day before we were to pick a jury to drop the charges, just a few days before trial. After, the DA even said to me, "I'm a dangerous man to make an enemy of." I think I was 20, so obviously I was cocky and snapped back "So am I," and stormed off. I not live a thousand miles away from that crappy little town.
Can the DA's past history be used as evidence in future cases to show they're not credible?
Should reply "and you have made an enemy today."
I'd like to see a three way verdict: guilty/not guilty/innocent.
An innocent verdict would mean the defendant had proven beyond a reasonable doubt that they did not do the act and would put the state on the hook for all costs. A jury that hung between not guilty and innocent would be considered to be not guilty, no retrial. Reality works better when misdeeds carry costs for those who commit them.
I would be interested to know from him why he, personally, felt that you defending your innocence made you his enemy.
