As others have said, you should have hired an attorney specializing in DUI cases. But it seems you know that already.
I feel like the camera showing my roadside test would go a long way if those blood results did not say what was presented in court.
This is a good example why you needed an attorney. If the blood tests truly did not say what was presented in court it doesn't matter what the camera shows. If they present evidence you can show is false, you immediately move to have the charges dismissed.
If they didn't present certified test results move for immediate dismissal, not a continuance to let them get their shite together. Get the lab tech on the stand if you can.
The camera footage doesn't mean jack, your goal is not to show you were "really okay", your goal is to show the prosecution doesn't have evidence to convict.
