62 [101 Op. Att’y
Six years after Olmstead, Congress enacted the
Communications Act of 1934, which made it unlawful for any
“person” to “intercept” and “divulge or publish” the contents of any
wire or radio communication without the authorization of the
sender. Pub. L. 73-426, Title VI, § 605, 48 Stat. 1103 (June 19,
1934), codified at 47 U.S.C. § 605. Soon thereafter, the Supreme
Court held that the statute, because it applied to any “person”
without exception, prohibited the use of wiretaps by law
enforcement personnel, and rendered inadmissible in federal court
any evidence obtained as a result of a wiretap. Nardone v. United
States, 302 U.S. 379, 382-83 (1937); see also Nardone v. United
States, 308 U.S. 338, 340-41 (1939).
Despite the prohibition on wiretapping in the Commun-
ications Act, many law enforcement officers continued to conduct
wiretaps, though it remained a “somewhat stigmatized”
investigative technique. Kaplan at 3; see also, e.g., Congressional
Wiretapping Policy Overdue, 2 Stan. L. Rev. 744, 748-50 (1950)
(explaining that wiretapping was common at the time and that the
U.S. Attorney General had interpreted the Communications Act to
prohibit only the divulging of information gleaned from the
wiretap, not the wiretapping itself). Then, by the 1950s and 1960s,
public attitudes became more accepting of the practice, in part
because the government found itself “struggling to enforce laws
against organized crime, drug trafficking, and other highly
dangerous criminal activities.” Kaplan at 3. Some states thus
began experimenting with their own wiretap statutes. Maryland,
for example, enacted a law in 1956 that authorized law enforcement
personnel to conduct wiretaps only if they received the functional
equivalent of a warrant based on probable cause from a circuit court
judge. 1956 Md. Laws, ch. 116, codified at Md. Ann. Code, art. 35
§§ 100-107 (1951, 1956 Cum. Supp.); see also Manger v. State,
214 Md. 71, 75 (1957) (discussing the enactment of the Maryland
law); 53 Opinions of the Attorney General 456, 458-59 (1968).
Meanwhile, the Supreme Court revisited Olmstead and
effectively overruled its holding that a wiretap is not a search
within the meaning of the Fourth Amendment. See Berger v. New
York, 388 U.S. 41, 51 (1967); Katz v. United States, 389 U.S. 347,
353 (1967). In Berger, the Court invalidated New York’s wiretap
statute, which had authorized wiretapping pursuant to a state court
order, but identified circumstances under which such a statute
would be constitutional. Berger, 388 U.S. at 54-63. Using Berger
as a guide, Congress passed Title III of the Omnibus Crime Control
and Safe Streets Act, which, as amended, continues to govern
wiretaps today. See Pub. L. 90-351, Title III, 82 Stat. 211 (June 19,
