You have the right to remain silent, but only if you tell the police that you’re remaining silent.
You have a right to a lawyer — before, during and after questioning, even though the police don’t have to tell you exactly when the lawyer can be with you. If you can’t afford a lawyer, one will be provided to you. Do you understand these rights as they have been read to you, which, by the way, are only good for the next two weeks?
