People who can’t afford a lawyer will have a public defender appointed. Virtually none of these cases involves expert testimony. My wife did a pro bono murder trial a couple of years ago. (If your case is at all interesting high end law firms will often represent you for free.) They showed the jury CCTV from all over the city literally following the accused from murder scene to his house. Just cutting from one camera to the other showing the jury exactly what happened after the murder.
Instead of recycling conventional wisdom, head over to your local federal court and sit in on some sentencing hearings (these are public). There will be a plea colloquy with the accused and the prosecutor will lay out all the supporting evidence. It’s quite eye opening.
