What should I do if I am being questioned?
Do not answer questions, do not volunteer.
Tell the police that you will not answer any questions without an attorney present.
It is the most natural thing in the world to try to defend yourself when you're being accused of a crime. And that's okay, and that's how it should be.
The thing to remember is time and place.
The time of your arrest, it is not the place to defend yourself. You cannot talk the police out of arresting you.
The correct time and place is in a courtroom.
