My question involves criminal law for the state of: Indiana
I am a complete and legally certified volunteer firefighter that was recently pulled over by police shortly after using the blue and white emergency lights on my car. He asked if I had any card or paperwork that gave me permission to have and use blue lights. I told him my fire department did issue us cards that gave us permission however it was expired and they had not given us updated cards yet. In my extreme nervousness of the moment I forgot about another card that I DID HAVE ON MY PERSON that gives me permission. Because I was unable to provide legal proof that I had permission to have and use blue lights, the officer gave me a class D felony for impersonating a public servant(firefighter not officer)and a class A misdemeanor for having blue lights in my vehicle. Later that day I realized the mistake I had made however by the time I was able to contact the officer it was too late because he had turned it over to the prosecutor. I am going to plead not guilty however I was wondering if anyone thinks I should get a lawyer or not. This is my first offence of such magnitude over a speeding ticket here or there. Any and all advice able to be given would be greatly appreciated.
