Your constitutional right to due process means you ALWAYS get a chance to tell your side of the story when you've been charged with any violation of law, regardless of whether it's classified as a CI, a misdemeanor or a felony. This isn't Russia...................................yet. You clearly can't ask yourself questions, so that's not part of the equation. In a jury trial, you'd make your case in your opening statement and closing argument. You'd build your case in between by asking the appropriate questions of the law enforcement officer on the stand. And as any first year law student will tell you: you don't ask any question you don't already know the answer to.
