William O. Douglas,
Draper v. United States (358 U.S. 307…
“ The round-up or dragnet arrest, the arrest on suspicion, for questioning, for investigation or on an open charge all are prohibited by the law. It is undeniable that if those arrests were sanctioned by law, the police would be in a position to investigate a crime and to detect the real culprit much more easily, much more efficiently, much more economically, and with much more dispatch. It is equally true, however, that society cannot confer such power on the police without ripping away much of the fabric of a way of life which seeks to give the maximum of liberty to the individual citizen. ”
