Anyone who watches TV knows that if you are arrested the cops will read you your rights, which includes the right to an attorney, one of which will be appointed to represent you if you cannot afford to hire one.
What happens in real life? You are arrested, and you assert your right to an attorney. The cops will probably try to talk you out of it (“just tell us what happened. we won’t be able to help you with this if you get a lawyer…”) but you insist. Then what? Do they hand you the yellow pages and a phone? Do you have to name a specific attorney if you say you want to hire one? Suppose you already have a lawyer, but for whatever reason you can’t reach him? Does everything stop until he turns up? Or can you keep calling lawyers until you wake up somebody who will take your case? Suppose you don’t have a lawyer and don’t even know how to find one? Are the cops suppose to give you guidance? Who decides whether you can afford a lawyer, and what standard to they use? (I might be able to afford a lawyer for a traffic charge, but I don’t think I could afford an all-out murder defense.) Can you be arraigned without a lawyer? If that happens, do you tell the judge that you have no lawyer and say nothing else? Do you get to talk to the public defender automatically, or is there a screening process? What really happens after they read you your rights?
