TERRE HAUTE, Ind. - Death row inmates at the federal prison in Terre Haute are routinely denied access to medical, dental and mental health care, the American Civil Liberties Union said Wednesday in a letter to a governmental official.

One diabetic prisoner showing symptoms of high blood sugar had to wait two hours to be treated with insulin, the ACLU said after a yearlong investigation. And some prisoners with dental problems chose simply to have all their teeth removed rather than suffer pain while waiting for complicated procedures, it said.
