I understand that when a defendant is charged with one or more crimes, one of the following outcomes almost always occurs in practice: either
1 . They plead not guilty to all charges and go to trial, or
2a. They plead guilty to all charges and bypass the trial, or
2b. They plead guilty to some charges, the prosecution agrees to drop the other charges, and they bypass the trial.
A. Is it procedurally possible for the defendant to plead guilty to all charges but still insist on going to trial anyway (e.g. if the defendant believes that the judge will impose a sentence that is fairer than any that the prosecution would agree to)? If so, does this ever actually happen?
B. Suppose that the prosecution files multiple charges, and the defendant is willing to admit guilt to some charges but not to others, but the prosecution is unwilling to settle without a conviction for certain charges for which the defendant maintains innocence. Is it procedurally possible for the defendant to plead guilty to some charges but not guilty to other charges in a trial? If so, does this ever happen?
C. If it is procedurally possible for the defendant to plead guilty to certain charges during a trial, does the jury render a verdict on those charges? Is the jury allowed to find the defendant not guilty, against the defendant's own plea? If so, does this ever happen?
