It would not be likely that she could get the case dismissed at all, it would be an issue of whether there is reasonable doubt... which is something that must be determined by trial.

Do you think we have a good chance of getting decent representation from a public defender if we want to challenge this and, if not, can you provide some advice on how to weed through the advertising and choose a competent and affordable attorney?
In my opinion, public defenders usually do a pretty good job, but it does depend on where you are and what the caseload is like, etc.
