Legal Question in Criminal Law in California

Unless the defendant hires an attorney, odds are they'll get away with it.

It depends on what the errors are. If the officer is a terrible speller and every other word is wrong, does that change the underlying facts? No.

Or are they factual errors that cast serious doubt on the accuracy and truth of the rest of the report and undermine the integrity of the investigation?

There is no short answer. Your defenses are nest explored by your attorney.
