I wouldn't mind. Peoples' lives are on the line. I'd rather it be 99.99% right than the 90% as it currently is.
The justice system has two basic functions: to punish the guilty and protect the innocent. False positives means there is a trade-off between how well it can do both functions at the same time. Society makes the decision about the appropriate balance between the two. If courts make it too burdensome to prosecute and punish the guilty, people will respond with harsher laws, longer sentences, etc. You might be okay with setting the burden at 99.99% certainty, but the history of votes on the issue suggest that most Americans want a lower burden than that.
