The only way you can possible get this case dismissed without plea bargaining for a deal, is by a lack of evidence. Since the video doesn't actually show you taking the earrings, that's good for your case. However, if the earrings were found on you, that video would likely lend credence to the fact that you stole the video. If you decided to take the case all the way to trial, you probably won't win if this is the case.
Um, OP admitted to the theft and turned over the merchandise. Do you believe there needs to be more evidence than that?
