There is no reason to be dishonest with your attorney. Your lawyer needs to know all the facts about your arrest, the crime you are charged with, and what you actually did. Your attorney/client privilege means that anything you discuss with your lawyer will be completely confidential, so you will not need to worry about telling them something that could be considered incriminating. By understanding all the facts, your lawyer can help you determine the best strategy to help you minimize the potential consequences you may face.
