WASHINGTON (AP) - A Justice Department official says the Boston Marathon bombing suspect will not be read his Miranda rights because the government is invoking a public safety exception. That official and a second person briefed on the investigation says 19-year-old Dzhokhar Tsarnaev will be questioned by a special interrogation team for high-value suspects. The officials spoke on the condition of anonymity because they weren't authorized to disclose the information publicly. The public safety exception permits law enforcement officials to engage in a limited and focused unwarned interrogation of a suspect and allows the government to introduce the statement as evidence in court. The public safety exception is triggered when police officers have an objectively reasonable need to protect the police or the public from immediate danger.
