I was on the beach with friends after hours and received a citation. When collecting identification, the officer called two of us out (including myself) to come to his vehicle. In the middle of talking with him about helping to remedy the situation, he drove his vehicle away while we were still next to it, pulling us with the car. Officers threw my friend down, and arrested him on the spot. It did not appear that he had done anything wrong, and so I (albeit unwisely) voiced my frustration with the officer. I was then arrested and charged for obstructing governmental administration. How serious is this charge and what are usually the consequences? What's my best way to better educate myself before appearing in court? THANK YOU!
