The sole issue on appeal is whether evidence seized in violation of the Fourth Amendment to the Constitution of the United States and art. 14 of the Massachusetts Declaration of Rights should be excluded from a proceeding to revoke probation. We transferred the appeal to this court on our own motion. We conclude, as do a majority of jurisdictions that have considered the issue, that, where the police who unlawfully obtained the evidence neither knew nor had reason to know of the probationary status of the person whose property was seized, the evidence is admissible in a proceeding to revoke probation.
While on probation for prior drug-related convictions in the Westborough Division of the District Court Department, Eva M. Olsen was arraigned on three new drug-related indictments in the Superior Court in Worcester County. A District Court judge held a surrender hearing on the same day the indictments *492 were returned. A police officer testified that drugs and paraphernalia were seized from Olsen’s home pursuant to a search warrant. Olsen indicated her intention to file a motion to suppress that evidence in the trial on the new indictments. 1 The judge found that Olsen had violated the terms of her probation but continued the disposition of the matter.
At trial, the judge allowed Olsen’s motion to suppress all the evidence. 2 The Commonwealth informed the judge that it would not appeal the suppression and that it had no other evidence with which to convict the defendant. The judge dismissed all three indictments with prejudice. On the same afternoon, Olsen’s probation in the District Court was revoked on the basis of the same evidence that the trial judge had suppressed.
Olsen concedes that the majority of jurisdictions, including the Federal courts, that have considered the question have decided that the exclusionary rule does not apply to probation revocation proceedings. The reasons for not excluding the evidence in a probation proceeding based on violation of the Fourth Amendment are the same as those based on the Fifth Amendment. See
Commonwealth
v.
Vincente, ante
278 (1989). Olsen argues, however, that art. 14 may provide broader protection to probationers than the United States Constitution. See
Commonwealth
v.
Fini,
*493
In Federal law and in most jurisdictions, the exclusionary rule does not apply as a matter of course to probation revocation proceedings because the “application of the exclusionary rule is restricted to those areas where its remedial objectives are thought most efficaciously served.” See
Commonwealth
v.
Vincente, supra
at 280, quoting
United States
v.
Calandra,
A probation revocation proceeding is not a criminal trial.
Gagnon v. Scarpelli,
We weigh this overwhelming State interest in admitting all reliable evidence against the deterrent purpose of the exclusionary rule. Most courts have concluded, and we agree, that a police officer’s “zone of primary interest” is in gathering evidence with which to convict a defendant of crime.
Bazzano, supra
at 832, quoting
United States
v.
Janis,
*495
Olsen argues, however, that concern for judicial integrity precludes the use of illegally obtained evidence in any court proceeding whatsoever. See
Elkins
v.
United States,
Our decision in
Commonwealth
v.
Fini, supra,
is not to the contrary. In
Fini,
we concluded that evidence obtained through illegal electronic eavesdropping in a private home is inadmissible, under art. 14 of the Declaration of Rights, to impeach a defendant’s testimony at trial. See
Commonwealth
v.
Blood,
We note that this case does not involve egregious police conduct,
Thompson
v.
United States,
Our decision protects the availability of probation for offenders. If we were to exclude that evidence from probation revocation hearings, there might be a disinclination to order probation in the first place. See
People
v.
Dowery,
Order revoking probation affirmed.
Notes
The Commonwealth argues that Olsen’s failure to move to suppress the evidence at the surrender hearing constituted a waiver of the issue. However, the record shows that she raised the issue and asserted her belief that the evidence was inadmissible at the surrender hearing. We assume for purposes of this appeal that her actions were adequate to preserve the issue.
The reason for suppression does not appear in the record. The record reveals that the officer knew of Olsen’s arrest but not of her probationary status.

concerned revocation of parole.
Gagnon
expressly equated the due process requirements, applicable to proceedings for revocation of parole, with those applicable to proceedings for revocation of probation, stating that neither is “a stage of a criminal prosecution, but [both do] result in a loss of liberty.”
