If you have been contacted by a private investigator about an alleged forged driving under the influence of alcohol or a controlled substance about the community service hours that you were supposed to do as part of your plea, I recommend that you first retain a criminal defense attorney to deal with the situation that you are writing about as opposed to meeting with the private investigator.My experience is that in the circumstances that you are writing about it is best for an attorney representing you to handle the situation as opposed to yourself. Based upon what your attorney advises you, you should follow his or her advice.
