At a press conference Tuesday afternoon, Attorney General Eric Holder, DHS Secretary Janet Napolitano, FBI Deputy Director John Pistole and New York Police Commissioner Ray Kelly updated reporters on the ongoing investigation into the attempted bombing in Times Square.
They said the suspect, Faisal Shahzad, was interviewed by the FBI under the Public Safety Exception rule before being read his rights. Pistole said Shahzad, a naturalized American citizen, cooperated with investigators both before and after being Mirandized, and Holder said the interviews provided “useful information.” Pistole declined to say how long Shahzad was questioned before he was read Miranda rights.
From the 1984 Supreme Court ruling on New York v. Quarles:
The doctrinal underpinnings of Miranda do not require that it be applied in all its rigor to a situation in which police officers ask questions reasonably prompted by a concern for the public safety.
