Hi flymo,
The police and CPS take domestic violence very seriously you have admitted to assault ( 39 ) and then resisted arrest
assaulted a police officer.
What do you think the court will think.
Was any other witnesses present, why did you not just go with the police?
I think it unlikely you will go to prision but expect to be dealt with severely - 6 months ago you were cautioned and the court will see this incident has not learning your lesson.
Domestic relationships are the most difficult to deal with but the well being of the children is the most important thing. What do you think your child think of you headbutting a policeman?
Be prepared for a hard time at court
