Glass chess

Fresno DUI Lawyer Jonathan Rooker: Fresno area law enforcement agencies have some of the strictest DUI enforcement policies in the Nation. The first decision an officer makes during the DUI enforcement is the decision to stop the vehicle. It may be a driving pattern, maintenance infraction, tinted windows, or other issues the lead the officer to make that decision. The next decision is whether to have the driver exit the vehicle and conduct a DUI investigation. Factors include odor or alcohol, red watery eyes, and slurred speech. Timely stopping, parking, and fumbling with a license or insurance paperwork, all influence the officers decision to continue the investigation. Once outside the vehicle the subject may sway or have trouble following directions. At the conclusion of the third stage, the officer decides if there is probable cause for an arrest. If you are arrested, there are steps you should take on your own behalf. It is important for anyone cited for DUI to contact the DMV within 10 days to preserve their right to an Admin Per Se Hearing in front of a DMV officer. Failure to contact the DMV within 10 days may result in the suspension of your driving privilege. Remember, the officer arrests at probable cause, but it takes proof beyond a reasonable doubt to convict. If the officer does their job right, a large percentage of the people should be found not guilty.

D v

Fresno & Madera Criminal Defense Lawyer Jonathan Rooker: Domestic Violence (DV) charges, punishments, and your rights is something you need to understand if you've been accused. DV charges can result in a sentence of probation, jail, and/or prison. DV can be charged under various sections including PC 243(E) or the more serious PC 273.5 Felony (DV) accusation. Many convictions result in being sentenced to a 52-week program, referred to as the Batterers Treatment Program (BTP). The right to own, possess, or use a Firearms, a serious issue for many people who grew up in the rural valley hunting, fishing, and target shooting can be lost forever. While Judges routinely advise those convicted of misdemeanor Domestic Violence that they will be prohibited from owning firearms for 10-years, the Federal Government will preclude gun ownership for the remainder of the persons life if they are convicted of a misdemeanor crime of domestic violence. It is important that the court knows you are a law abiding, upstanding, and productive member of society. Don't let an accusation turn into a lifetime of being stigmatized as a criminal.
