Mose Franklin Pearson and Edward King were convicted of the importation of heroin, and of the use of the United States mail to further such importation, possession and distribution, under 21 U.S.C. §§ 952(a), 843(b), and 841(a)(1). They appeal, alleging that the government imprоperly obtained the heroin introduced into evidence against them. Finding that the government exceeded neither statutory nor constitutional limits, we affirm.
Viewed in the light most favorable to the government,
Glasser v. United States,
On December 4, Leo Lyle, the branch’s acting manager, removed ten of these envelopes from the normal mail channels for possible inspection because they felt “thicker than an ordinary Christmas card.” The envelopes had entered the United States at San Francisco and been routed to Birmingham without having been inspeсted. Lyle then gave the envelopes, which bore a single return address and the names of six senders, to a postal inspector, who in turn passed them on to Customs Supervisor Charles Sheehan and Agent Bernie Fenger of the Drug Enforcement Administration.
Agent Fenger first examined the envelopes by tapping them on a hard surface to test for any shift in position of an enclosed'substance; the tapping produced a distinct pocket or cushion of powdery material. Sheehan immediately opened the envelopes, finding in each one a Christmas card which in turn held an inner packet containing a white powder; the substance responded positively to a field test for opium derivatives. The men rеmoved a sample from each of the packets, replaced the packets in the envelopes and returned the envelopes to the Postal Service for delivery.
We need not trace the history of this case any further, since the only issue on *352 appeal is the legality of this search. It is sufficient to note that the opening of these envelopes represented the beginning of an investigation which terminated in the arrest of appellants and of two other co-defendants.
I
Statutory authorization for the search is found in 19 U.S.C. § 482 (1965), which provides, in pertinent part, that a customs officer may “search any trunk or envelope, wherever found, in which he may have a reasonable cause to suspect there is merchandise which was imported contrary to law . . ..”
Appellants’ argument that this section authorizes searches only in border areas seems to us without merit. It is true, of course, that most customs searches tаke place in such areas, but the very words of the statute negate an interpretation that would deny to • agents the authority “to search any trunk or envelope, wherever found . . . assuming of course that the other requisites for a valid customs searсh are met (emphasis supplied). Additionally, the statute specifically empowers customs officers to make, such a search, “as well without as within their respective districts . . ..”
Whether the government inspector had the required “reasоnable cause to suspect” is likewise a question which need not long detain us. Case law emphatically demonstrates that much less than probable cause will suffice. In
United States v. Doe,
Sheehan likewise had “reasonable cause” to open the envelopes in question. The pattern of mail deliveries (numerous card size envelopes from a small group of senders with identical overseаs addresses) is itself somewhat suspicious. When this factor is considered along with the envelopes’ unusual thickness and the powdery cushion which appeared as the envelopes were tapped, it is apparent that Sheehan acted properly.
II
We must next determine whether the opening of the envelopes violated appellants’ Fourth Amendment rights.
The government has a traditional and well recognized right to examine both persons and merchаndise entering the country.
See Cotzhausen v. Nazro,
No court, however, has yet confronted the situation posed by this case, in which the search does not take рlace at a port of entry or border area. The question for decision is thus whether, given that the search would have been reasonable by Fourth Amendment standards if it had taken place in the San Francisco post office, it bеcame unreasonable as a result of being conducted in Birmingham.
Appellants argue strenuously that reversal of the district court is compelled by
Almeida-Sanchez v. United States,
It is true that the rationale of
Almeida-Sanchez
is that the Fourth Amendment’s standards of reasonableness for searches at a border or its functional equivalent differ from the standards applicable to searches in the interior of the country, but the bases for this distinction are inapposite here. First, since travellers are aware that they may be subjected to a customs inspection at the border, they do not have a reasonable expectation of privacy as they do when travel-ling in the country’s interior,
cf. Katz v. United States,
None of these factors requiring reversal in Almeida-Sanchez is present here.
1
In the first place, of course, the letters themselves hаve no rights; it is the rights of their sender and addressee with
*354
which we are concerned. Appellants here could have had no reasonable expectation that their letters, mailed from abroad, would remain uninspected.
See United States v. Odland,
The government’s interest, by contrast, is equally strong and is served equally well whether the search occurs in California or Alabama.
2
And since nothing can be added to or taken from an envelope whilе it is in transit, and since postmarks clearly identify envelopes from abroad, there is no danger analogous to that presented in
Almeida-Sanchez
that the government will search envelopes not “within the proper scope of official scrutiny . . ..”
Almeida-Sanchez
v.
United States,
Thе search at issue is more comparable to the search approved by this court in
United States v. Chiarito,
For the reasons stated, the decision of the district court is
Affirmed.
Notes
. Nor is appellants’ argument strengthened by Almeida-Sanсhez?s progeny. In
United States v. Ortiz,
- U.S. -,
United States v. Brignoni-Ponce,
- U.S. -,
. We do not rest our decision on the grounds that the search occurred at the functional equivalent of a border, but we note that the factual situation was quite similar to one given as an example in
Almeida-Sanchez, supra,
