There has been another assault on our Bill of Rights ("Court Gives Leeway to Interrogate," May 28). In its recent ruling, the U.S. Supreme Court held in the case of Chavez vs. Martinez that the police and government investigators can force a person to talk, as long as those admissions are not used to prosecute the person. According to your article, Justice Clarence Thomas' view is that "despite a common perception, the Constitution does not bar police from using pressure -- short of torture -- to obtain information from suspects or witnesses." It seems that another common perception is that we live in a free country and under the protection of the Bill of Rights. That perception also is no longer true.
