No! Think of the possible consequences of getting a criminal record. It will affect your professional life and, if you ever have to find work again, not a lot of companies will accept ex-convicts as employees. Your relationships will also be greatly affected, especially the ones with your family and close friends. In the end, you have a lot more to lose if you plead guilty.
It is better to consult with a criminal lawyer first before making any pleas. A good criminal defence is usually very technical and a good criminal lawyer may still be able to find a technicality that can get you off the hook and help you prove your innocence.
