Lawyers aren't just for the guilty. Even if innocent, a lawyer protects your rights, makes sure proper procedures are followed, stops you from saying stupid things that can be misinterpreted, explains to you what is going on. And a big-name attorney may have fallen in their lap because of the publicity of the case.
Get used to me. Black, confident, cocky; my name, not yours; my religion, not yours; my goals, my own; get used to me. -Muhammad Ali
