Was the video evidence preserved?
If you had hired a lawyer the day of or even the day after the first thing the lawyer could have done is perpetuate that video evidence to make your case defense.
So, what is your question?
NOT LEGAL ADVICE. FOR EDUCATION AND INFORMATION ONLY. Mr. Rafter is licensed to practice in the Commonwealth of Virginia and the US Federal Courts in Virginia. There is no implied or actual attorney-client relationship arising from this education exchange. You should speak with an attorney licensed in your state, to whom you have provided all the facts before you take steps that may impact your legal rights. Mr. Rafter is under no obligation to answer subsequent emails or phone calls related to this matter.
I do not understand what you are asking. You were not charged with assualt, but disturbing the peace. Aggresiveness is not an element of Distrubing the Peace. If you insist on representing yourself, you should probably read the statute and see what the elements of the crime actually are.
