Cases cited there are ...

Olmstead v. United States, 217 U.S. 438 (1928)
U.S. v. Butenko, 494 F.2d 593 (3d Cir. 1974) (en banc), cert. denied, 419 U.S. 881 (1974)
Ivanov v. United States (5th Cir., 1974) no citation found
Chagnon v. Bell, 642 F.2d. 1248, 1266 (DC Cir. 1980), cert. denied, 453 US 911 (1981)

Giordano v. United States, 394 U.S. 310 (1969)

But 10 years of experience here have taught me that the most carefully written opinions are not always carefully read - even by those most directly concerned.

One more ...

Alderman v. United States, 394 U.S. 165 (1969)
