For example, if a police officer was caught doing 100 mph in a 50 mph zone, the department could force him to talk about the incident if the answers are used for internal charges. He could be terminated for refusing to answer. If the department is questioning him for criminal charges, then they must advise him of the Miranda warning.
Voting:
"The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of race, color, or previous condition of servitude."
The Fifteenth Amendment doesn't say voting can't be denied because of age. The Second Amendment, however, states "shall not infringe".
