Legal Question in Criminal Law in California

Nothing you have written suggests that the evidence was insufficient. Defendants often don't call any witnesses; that does not mean they can't be convicted. You complain that other types of evidence were absent, but what really matters is what the prosecutor *did* introduce, not what she didn't.

Of course, you haven't told us much about the case. If I knew more I might see a promising argument for an appeal even though I don't see one yet.
