Defendants appeal from judgments of conviction following trial by the court. All three defendants were convicted of bookmaking (Pen. Code, §337a, subd. 2); of conspiracy to obtain telephone service by fraud (Pen. Code, § 502.7, subd. (a), 502.7, subd. (b)); of conspiracy to commit the offense of unlawful use of telephone lines and equipment (Pen. Code, § 591); and of conspiracy to illegally wire tap. (Pen. Code, § 640.) For the reasons hereinafter stated, we have concluded that the judgments must be affirmed.
Facts
A multi-frequency signal generator or “blue box” is a device designed to enable the user to avoid long-distance telephone charges. The user first dials a toll-free long-distance information number. Then he activates the “blue box” to produce a 2,600-cycle tone which terminates the connection with the information operator although the user still has access to the open trunk line. As long as the line is held open the user can utilize impulses from the “blue box” to place any number of long-distance telephone calls without the telephone company having any record of areas called or charges incurred. The telephone company records simply indicate that a free call has been made from a given telephone number. On occasion, in order to determine if there is trouble on the lines, the telephone company “prints out” the unbilled computerized data pertaining to toll-free information calls. From April through November 1966 such “print outs” indicated that 2,020 long-distance information operator calls were made from number 361-1261. Defendant Garber was the subscriber to this telephone number. A number of the calls were unusually lengthy. The “print outs” also showed that from August to November 1966 approximately 40 such long-distance operator calls were made from another number (377-4275) listed to defendant Garber. Other computer “print outs” indicated *124 345 information calls made in a two-month period from one telephone number listed to defendant Noto and 14 such calls from another number of his. Some of these calls were of an unusual length. Still other “print out” information obtained by the company showed numerous long-distance calls from numbers listed to defendant Garber under a false name and installed in apartments actually rented to defendant Teran. The telephone company next checked the telephone lines and discovered no trouble in the lines.
The telephone company began monitoring one of Garber’s numbers (371-1261) on October 24, 1966, using a device designed to monitor only those outgoing calls commencing with the 2,600-cycle tone generated by the “blue box.” After about 28 hours of actual monitoring, this procedure was discontinued on November 2, 1966. During the time the company was monitoring, only 65 minutes in “blue box” calls were actually overheard and recorded by the company. Apparently none of the other aforementioned numbers were monitored.
On November 29, 1966, the telephone company met with law enforcement officials and informed them that they had the “print out” information indicating the use of “blue boxes” at the residences of all three defendants. The telephone company representatives also informed the officials that they had monitored the one telephone at defendant Garber’s residence. At this time company representatives did not divulge the contents or subject matter of the recordings made during the monitoring procedure. The district attorney made a written demand for the recordings and they were subsequently produced on November 30, 1966. The recordings were introduced in evidence at the grand jury hearing as well as at the trial and it was stipulated at the trial that these recordings clearly indicated bookmaking activities. The admission of this evidence was over the objection of all defendants.
On December 11, 1966, a warrant was procured for the search of the premises at 2395 New Jersey Avenue, San Jose, the residence address of defendant Garber. On the morning of December 12, 1966, San Jose police officers went to the address to execute the warrant. Although they had information that defendant Garber was not at home, the officers went to the door and rang the bell. After receiving no response they rang the bell a second time. They then heard some unintelligible noises in the house, the sort of noises which indicated movement within the house. One of the officers then kicked open the door so that an entry could be made. Mrs. Garber and a *125 minor child were in the house. They had apparently been bathing. Approximately 40 seconds elapsed between the forced entry and the first ringing of the doorbell. In the search that followed, the officers found one piece of lined paper with first names, initials and telephone numbers, one piece of lined paper with defendant Note’s name and a series of telephone numbers; a long-distance telephone bill with defendant Note’s name, a newspaper clipping concerning wiretapping and some printed sheets on “Bowl Games.” The officers also saw a box similar to a “blue box” but did not seize it. The items taken were admitted into evidence before the grand jury and at trial defense counsel objected to their admission on the ground that the officers had not properly identified themselves pursuant to the provisions of Penal Code section 1531.
On December 11, 1966, a warrant for the search, of the Santa Clara premises of defendant Noto was also obtained. The warrant was executed on the morning of December 12, 1966, at which time defendant Noto admitted the officers. During the search a number of dated publications entitled “The National Daily Reporter” were found. Accounting sheets and other bookmaking paraphernalia were also uncovered. A “blue box” was also discovered and seized. These items were all introduced into evidence at the grand jury hearing.
No warrant was obtained for the search of the apartment of defendant Teran. Police began surveillance of this apartment on the evening of December 11, 1966. The next morning the telephone company put its monitoring device on the telephone line to this apartment. A little after 10 a.m., by use of this monitoring equipment, a telephone company representative heard the 2,600-cycle tone emitted by a “blue box.” Law-enforcement officials were informed but no record of calls was made because the equipment was not properly adjusted. By prearrangement police officers were advised that the device was being used and they then went to the apartment. The officers knocked on the door and defendant Teran appeared at a window and asked who was there. One of the officers held his sheriff’s identification card to the window for Teran to read. Teran then disappeared and when there was no further response, the officers forced entry. Defendants Garber and Teran were both found in the apartment. An adding machine and almost $3,000 in currency was discovered. Two of the “blue box” devices were also recovered, along with a number of racing journals and betting records. Both Teran and Garber were placed under arrest. At trial, counsel for defendant *126 Teran objected to the admission of this evidence.
A Federal Bureau of Investigation specialist in bookmaking investigation testified before the grand jury to the effect that the material recovered during the searches was used for bookmaking activity.
Contentions
All defendants contend that the convictions- must be reversed because they are based on evidence obtained in violation of 47 U.S.C.A. section 605- prohibiting the unauthorized publication or use of certain communications by wire or radio, and that the monitoring procedure violated the right of privacy guaranteed by the Fourth Amendment. Defendants Garber and Noto also contend that the evidence obtained at Garber’s residence was inadmissible because the officers who executed the search warrant failed to comply with the provisions of Penal Code section 1531. Defendant Teran also argues that the evidence obtained at his apartment is inadmissible because the officers did not have a search warrant. At o-ral argument Teran also contended that the forcible entry of Teran’s residence was in violation of Penal Code section 844.
The Fourth Amendment
In
Katz
v.
United States
(1967)
We note, moreover, that although evidence obtained in violation of the Fourth Amendment is inadmissible in state courts, the amendment does not apply to searches by a private individual unless such individual is wilfully participating in a joint activity with a state agent who either requests the illegal search or has knowledge of it but fails to protect the third party’s rights.
(Stapleton
v.
Superior Court,
Applicability of 47 U.S.C.A. Section 605
Defendants contend that the tape-recorded conversations resulting from monitoring of defendant Garber’s telephone should have been excluded from evidence because they were obtained in violation of 47 U.S.C.A. section 605, which prohibits the unauthorized publication or use of certain communications. 2 This contention is without merit because at the time of the alleged violation the federal provision had no application to the admission of evidence in state courts.
In
Schwartz
v.
Texas
(1952)
We are satisfied, moreover, that under the facts of this case there was no violation of the statute on several grounds. We are particularly impressed by the holding in
United States
v.
Sugden,
We also agree with the analysis of
Hanna
that because the law requires telephone companies to discover illegal telephone calls (47 U.S.C.A., §§ 202, 203, 220) investigative work carried out to discover such calls has become a part of the transmission of communications. It was there held that “ ‘ a security officer, in the light of present day developments, should be included among company employees engaged in the transmission of communications. ’ ” (
In
Bubis
v.
United States,
The Arrest of Term
Defendant Teran contends that the officers did not have reasonable cause to arrest him and that the evidence obtained in the search of his residence should have been excluded because the officers did not obtain a search warrant, although the search had been planned for some time.
Turning first to defendant’s contention that there was no reasonable cause for the arrest, he notes that the officer in charge was informed by the telephone company security officer that the “blue box” at the Teran residence was in use on the morning of December 12, 1966, prior to the time the officers went to the premises. Defendant claims that the ‘ ‘ reasonable cause” to arrest was contrived and particularly emphasizes the fact that no recording of the communication in question was made. We find no merit in defendant’s argument and conclude that the information received from the telephone company security officer concerning the violation of the -wiretapping law provided sufficient probable cause to support an arrest. As we stated in
People
v. Gardner,
*130
Since there was reasonable cause for Teran’s arrest, a reasonable search incidental to his arrest was proper and not violative of the Fourth Amendment.
(United States
v.
Rabinowitz,
At oral argument we noted that in
Chimel
v.
California
(1969)
Compliance With Penal Code Sections 1531 and 844
Defendants Garber and Noto argue that the evidence uncovered during the search of Garber’s residence should have been excluded because the police officers made a forcible entry *131 in order to execute the search warrant. According to Penal Code section 1531, 4 ‘ ‘ The officer may break open any outer or inner door of a house ... to execute the warrant, if, after notice of his authority and purpose, he is refused admittance. ’ ’ As already noted, the officers forcibly entered the residence after ringing the doorbell twice in a 40-second period and after hearing some ‘ ‘ unintelligible sounds ’ ’ within the house.
Defendant Teran argues that the forcible entry into his residence was in violation of section 844 which provides, in pertinent part, that “. . . in all eases a peace officer, may break open the door or window of the house in which the person to be arrested is, or in which they have reasonable grounds for believing him to be, after having demanded admittance and explained the purpose for which admittance is desired. ’ ’
In proceeding to discuss these respective contentions we note, initially, that an entry of a house in violation of sections 844 or 1531 renders any following search and seizure unreasonable within the meaning of the Fourth Amendment.
(Greven
v.
Superior Court,
In
Greven
it was pointed out that the cases holding the requirements of section 844 satisfied by “ ‘substantial compliance’ ’’ involved situations where the officers actually identified themselves but failed to announce their purpose. (71 Cal.2d at pp. 291-292; see
People
v.
Marshall,
Here, with respect to the entry into Garber’s residence, the officers did not comply with section 1531 at all. It is clear that they gave no notice of their authority at any time prior to the entry, and that, accordingly, there was no compliance with the indispensable rule of announcement of authority delineated in Greven. We need not, therefore, discuss whether the circumstances excused compliance with the announcement of the purpose for the entry.
Accordingly, we hold that the entry in this ease was not effected in compliance with the provisions of section 1531, that the search and seizure which was undertaken subsequent to such entry was unreasonable and unlawful, and that the fruits of such search and seizure were inadmissible in evidence. Our conclusion, however, does not require a reversal because the error was harmless within the rule set out in
Chapman
v.
California,
Adverting to the entry of Teran’s residence, we perceive no violation of section 844. When the officers knocked at the door and Teran appeared at the window and asked who was there, the officers announced their authority when one of the officers held his sheriff’s identification card to the window for Teran to read. This satisfied the minimum compliance required by section 844 as delineated in Greven, supra. With respect to the second requirement of section 844 that the officers explain “the purpose for which admittance is desired,” due to exigent circumstances substantial compliance with the provisions of the section was achieved and literal compliance was not required. When Teran disappeared and made no further response after the officers identified themselves, these circumstances and the facts already known by the officers concerning the telephone monitoring and the use of a “blue box” at the Teran residence were such as to give rise to a reasonable belief on the part of the officers that a demand for admittance would be futile and that an entry without an express announcement of purpose was necessary to prevent the destruction of evidence and to discourage escape.
The judgments are affirmed.
Sims, J., and Elkington, J., concurred.
A petition for a rehearing was denied August 13, 1969, and appellants’ petition for a hearing by the Supreme Court was denied October 15, 1969.
Notes
The instant case was tried on October 30, 1967.
Seetion 605 of the Federal Communications Act provides, in pertinent part, “No person receiving or assisting in receiving, or transmitting, or assisting in transmitting, any interstate or foreign communication by wire or radio shall divulge or publish the existence, contents, substance, purport, effect, or meaning thereof, except through authorized channels of transmission or reception, to any person other than the addressee, his agent, or attorney, or to a person employed or authorized to forward such communication to its destination, ... or on demand of other lawful authority; and no person not being authorized by the sender shall intercept any communication and divulge or publish the existence, contents, substance, purport, effect, or meaning of such intercepted communication to any person
The Bubis court strongly suggested in a footnote (fn. 5, p. 648) that although the interception was lawful, it did not mean to suggest that the disclosure was lawful.
