This case presents the question whether a probationer was lawfully arrested pursuant to a probation-violation warrant when the probation-violation warrant was not sworn under oath. We conclude that, because a warrant is not required under the Fourth Amendment to make an arrest for a probation violation, it is irrelevant whether the warrant was properly issued in determining whether there was a Fourth Amendment violation. Accordingly, we reverse and remand.
Defendant was on probation in an unrelated case in the Washtenaw Circuit Court. His probation officer, Thomas Mihalic, requested an arrest warrant for probation violations. Mihalic utilized a standard State Court Administrator’s Office (SCAO) form entitled “Motion, Affidavit, and Bench Warrant.” That form alleged three reasons to arrest defendant and revoke his probation: failure to notify the probation officer of a change of address, commission of a crime (assault), and failure to comply with the requirement that he partid*497pate in an adult education or general equivalency diploma (GED) program. The motion and affidavit section was signed by Mihalic, but it was not subscribed and sworn under oath. The bench warrant portion was signed by the circuit judge in this case.
A few days later, defendant reported to Mihalic at the Washtenaw County Courthouse. Washtenaw County Deputy Sheriff David Anderson was summoned to place defendant under arrest. Deputy Anderson testified that the arrest was based on the warrant that had been presented to him by Mihalic. A search subsequent to the arrest conducted by Deputy Anderson yielded 35 packets of heroin. Defendant was charged with possession of heroin.1
Defendant moved to suppress the evidence on the basis that the search followed an unlawful arrest. The trial court thereafter granted defendant’s motion on the basis that the arrest warrant was defective because it was not supported by an affidavit made under oath or affirmation as required by the Fourth Amendment of the United States Constitution. The trial court also rejected the argument that the good-faith exception applied. The trial court dismissed the case without prejudice. The prosecution now appeals, and we reverse.
There are, in fact, a number of reasons why the arrest and subsequent search in this case was, in fact, lawful. For the reasons discussed below, we conclude that the trial court erred by granting defendant’s motion to suppress.
We begin by noting that the trial court did not conclude, nor does defendant argue, that there is any defect in the search aside from the arrest issue. That *498is, the only claim that the search was improper is based on the argument that the arrest itself was improper because of the fact that the warrant was not supported by an oath or affirmation. If we determine that the arrest was proper, then it will automatically follow that the search was proper. Similarly, there was no determination by the trial court, nor does defendant argue, that there was, in fact, a lack of probable cause to support the issuance of an arrest warrant. Rather, the trial court’s holding was based on a conclusion that the requirement of the Fourth Amendment that “no Warrants shall issue, but upon probáble cause, supported by Oath or affirmation” was not complied with regarding the oath or affirmation and, therefore, the arrest warrant was defective and the arrest under the warrant was unlawful. Indeed, the trial court even noted in its opinion on the motion to suppress that in the separate probation-revocation proceedings, defendant had pleaded responsible to the probation violations. Accordingly, we will proceed with our analysis under the assumption that there was, in fact, probable cause to believe that defendant committed the alleged probation violations listed in the warrant.
The first reason why this was a valid arrest is that an arrest warrant was not, in fact, required in this case. MCL 764.15(1)(g) authorizes an arrest without a warrant whenever a “peace officer has reasonable cause to believe the person . . . has violated 1 or more conditions of a. . . probation order imposed by a court of this state ....” As noted above, there is no argument in this case that there was, in fact, probable cause to believe that defendant had committed a probation violation or that the arresting officer had probable cause to so believe.
*499Although defendant acknowledges in his brief that probation-violation proceedings can be commenced without the issuance of an arrest warrant, he attempts to argue that that is irrelevant because a warrant was nevertheless obtained and was invalid. Defendant supports this argument with the observation that the arresting officer stated that the warrant was the only basis for the arrest. But, as discussed already, the warrant was not the only basis for the arrest. And the fact that the arresting officer may have erroneously believed that it was is irrelevant.
In Devenpeck v Alford,2 the United States Supreme Court addressed the issue whether an arresting officer must correctly identify the basis for an arrest in order for the arrest to be valid. In Devenpeck, the officer arrested the plaintiff for a violation of the Washington Privacy Act.3 The charge was subsequently dismissed, and the plaintiff filed suit, arguing that he had been arrested without probable cause.4 The United States Court of Appeals for the Ninth Circuit had ruled that the probable cause for the arrest must be related to the charge that the officer arrested the person for, or for a closely related offense.5 The Supreme Court disagreed, concluding that what matters is whether objectively there exists probable cause to believe that a crime has occurred, not whether the officer subjectively identified the correct crime:
Our cases make clear that an arresting officer’s state of mind (except for the facts that he knows) is irrelevant to the existence of probable cause. See Whren v. United States, 517 U.S. 806, 812-813, 135 L. Ed. 2d 89, 116 S. Ct. 1769 *500(1996) (reviewing cases); Arkansas v. Sullivan, 532 U.S. 769, 149 L. Ed. 2d 994, 121 S. Ct. 1876 (2001) (per curiam). That is to say, his subjective reason for making the arrest need not be the criminal offense as to which the known facts provide probable cause. As we have repeatedly explained, “ ‘the fact that the officer does not have the state of mind which is hypothecated by the reasons which provide the legal justification for the officer’s action does not invalidate the action taken as long as the circumstances, viewed objectively, justify that action.’ ” Whren, supra, at 813, 135 L. Ed. 2d 89, 116 S. Ct. 1769 (quoting Scott v. United States, 436 U.S. 128, 138, 56 L. Ed. 2d 168, 98 S. Ct. 1717 (1978)). “[T]he Fourth Amendment’s concern with ‘reasonableness’ allows certain actions to be taken in certain circumstances, whatever the subjective intent.” Whren, supra, at 814, 135 L. Ed. 2d 89, 116 S. Ct. 1769. “[EJvenhanded law enforcement is best achieved by the application of objective standards of conduct, rather than standards that depend upon the subjective state of mind of the officer.” Horton v. California, 496 U.S. 128, 138, 110 L. Ed. 2d 112, 110 S. Ct. 2301 (1990).[6]
While Devenpeck involved the question whether the arresting officer correctly identified the crime for which to book the suspect, and this case involves whether the arresting officer correctly identified the legal basis for the arrest, we do not believe that that supplies a meaningful difference. The Supreme Court clearly established that the Fourth Amendment creates an objective standard to determine whether an arrest was lawful, without regard to the arresting officer’s subjective belief. And the objective truth in this case is that the arresting officer had a legitimate basis to arrest defendant without a warrant. Therefore, the arrest was valid without regard to the officer’s subjective belief that he needed a warrant. In sum, the officer’s erroneous belief that a warrant was necessary, as well as any *501erroneous belief that the warrant was valid, is immaterial to the question whether the arrest was valid under the Fourth Amendment.
The next reason that this arrest was valid is similar to the first. One of the reasons for the probation violation was that defendant had committed an assault. An ordinary assault and battery7 is a misdemeanor punishable by up to 93 days’ imprisonment. And, as such, it too justifies an arrest without a warrant.8
Finally, the prosecution also argues that the principle discussed in Triplett v Deputy Warden, Jackson Prison,9 that the probable cause and oath or affirmation requirements of the Fourth Amendment do not apply to parole-revocation warrants, should also apply to probation-violation warrants. Defendant counters that Triplett is inapplicable here because, unlike a probationer, a parolee is considered to still be in custody, not just in prison.10 While the status of a probationer and a parolee are arguably different, that does not mean that the probationer necessarily enjoys the same Fourth Amendment protections as a member of the general public unencumbered by an order of probation.
In Triplett,11 this Court addressed a prisoner’s habeas corpus challenge. The prisoner argued, in relevant part, that his incarceration was unconstitutional because the warrant for his arrest for a parole violation was “not supported by a showing of probable cause or by oath or affirmation.”12 This Court, agreeing with federal au*502thorities, determined that the oath or affirmation requirements of the United States Constitution and the Michigan Constitution did not apply to a warrant for the arrest of a parolee for a parole violation.13 We find this analysis persuasive.
Probation is a matter of legislative grace. People v Johnson.14 Because it is a matter of grace, a defendant has no vested right in its continuance and the probation order remains at all times revocable and amendable.15 Similarly, a sentence of supervised release necessarily involves the surrender of certain constitutional rights. See People v Harper16 In addition, a probationer has a diminished expectation of privacy and, accordingly, may be subjected to searches that might be unreasonable if conducted on members of the general public. See United States v Knights17 In Knights, the Supreme Court of the United States explained that — at least with regard to searches — the “balance of governmental and private” interests warranted “a lesser than probable-cause standard” of protection under the Fourth Amendment; specifically, the Court held that a probationer has “significantly diminished privacy interests” so that an officer need only have a “reasonable suspicion” that the *503probationer is engaged in criminal activity before the officer could lawfully search the probationer.18
Moreover, the United States Supreme Court observed in Griffin v Wisconsin19 that “[t]o a greater or lesser degree, it is always true of probationers (as we have said it to be true of parolees) that they do not enjoy ‘the absolute liberty to which every citizen is entitled, but only . .. conditional liberty properly dependent on observance of special [probation] restrictions.’ Morrissey v. Brewer, 408 U.S. 471, 480 [92 S Ct 2593; 33 L Ed 2d 484] (1972).” In Griffin, the Court upheld a search of a probationer’s home without a warrant under the state’s probation regulations, as being reasonable under the Fourth Amendment.20 In so concluding, the Court rejected the need for a warrant, concluding that, in the context of probation supervision, a “warrant requirement would interfere to an appreciable degree with the probation system .. . ,”21
If the Fourth Amendment does not require a warrant to search a probationer’s home, then it is not unreasonable to conclude that it does not require a warrant to arrest a probationer. Therefore, given a probationer’s reduced privacy interests, we agree with the prosecution that the principle discussed in Triplett can be extended from parolees to probationers. As such, the oath or affirmation requirement generally applicable to warrants does not apply to a warrant for the arrest of a probationer.
Finally, even if we were to agree with defendant’s argument that under MCR 6.445(A) a probation viola*504tion proceeding must be commenced with either a summons or an arrest warrant and, if it is commenced with an arrest warrant, the warrant must be made under oath or affirmation, that does not support the conclusion that the arrest violated the Fourth Amendment. In Virginia v Moore,22 the Supreme Court considered a case where the defendant was arrested for a misdemeanor under circumstances in which a state statute required the issuance of a summons rather than a custodial arrest. A subsequent search of the defendant yielded cocaine.23 The Court concluded that, while states are free to impose additional restrictions on the arrest powers of the police, such restrictions do not alter the protections of the Fourth Amendment.24 That is, a violation of the additional state restriction does not violate the Fourth Amendment and, therefore, does not render invalid the search subsequent to the arrest.25 Therefore, even if we were to agree with defendant that the court rule creates a requirement that probation-violation proceedings must be commenced by either a summons or an arrest warrant, and that the warrant must be sworn to, a violation of such a requirement still would not amount to a Fourth Amendment violation that would render the arrest, and the subsequent search, constitutionally infirm.
For the above reasons, we conclude that it does not matter whether the arrest warrant in this case was unsworn because it was unnecessary for there to be a sworn arrest warrant. Defendant’s arrest was lawful under the Fourth Amendment and, therefore, so was the subsequent search.
*505In light of this conclusion, it is unnecessary to consider the prosecution’s second argument, whether the exclusionary rule should be applied in this situation assuming that the arrest was, in fact, unlawful.
For the above reasons, we conclude that the trial court erred by granting defendant’s motion to suppress the evidence.
Reversed and remanded for further proceedings consistent with this opinion. We do not retain jurisdiction.
