Tom C. Clark,
Miranda v. Arizona — Concurring part and dissenting in part
“ Nor can I join in the Court's criticism of the present practices of police and investigatory agencies as to custodial interrogation. The materials it refers to as "police manuals" [1] are, as I read them, merely writings in this field by professors and some police officers. Not one is shown by the record here to be the official manual of any police department, much less in universal use in crime detection. Moreover, the examples of police brutality mentioned by the Court [2] are rare exceptions to the thousands of cases that appear every year in the law reports. ”
