It is always a good idea to pull over when you are "bluelighted." If you don't, you can get arrested, which is bad. The police can ask you for your DL, registration and proof of insurance. You can get tickets if you don't have these documents available which can cost you $ which is also bad. It is not a voluntary and consesual process.
Felonies are recorded by the official court reporter. Misdemeanors are recorded digitally. You can order transcripts of the proceedings through the office mentioned by one of my fellow AVVO attorneys.You do have to pay a fee in advance. If the case is going up on appeal, ask your attorney about getting a copy of the transcript. It will save you $.
It sounds like you have defenses to your criminal charge. Sometimes the police make mistakes on these domestic cases. You should consider contesting the charges in court. If you need my help, call me at 407-831-3434.
