William O. Douglas,
Knauer v. United States — Opinion of the Court
“ For denaturalization, like deportation, may result in the loss 'of all that makes life worth living.' Ng Fung Ho v. White, 259 U.S. 276, 284, 42 S.Ct. 492, 495, 66 L.Ed. 938. Hence, where the fate of a human being is at stake, we must not leave the presence of his evil purpose to conjecture. ”
