dissenting, with HOLLAND, Justice, joining:
The majority opinion excludes evidence obtained from an administrative search of a probationer triggered by an inconclusive tip from a police officer notwithstanding an alternative reasonable basis for the search upon independent grounds. Probation officers had independent evidence that Cul-ver was using illegal drugs and had violat*16ed his curfew. Because the totality of the circumstances demonstrated that the probation officers’ decision to conduct the search of Culver’s residence was reasonable, we would affirm the denial of his motion to suppress the evidence obtained from that search. We would also affirm the denial of Culver’s motion to suppress his statements.
An administrative search requires both substantial compliance and reasonableness
This Court has recognized that “probationers do not have the same liberties as ordinary citizens” and has held that “administrative searches of probationer homes require only reasonable grounds, even if the probation officers do not satisfy each technical requirement of the search and seizure regulations of the Department of Correction.”22 The special nature of probationary supervision justifies a departure from the usual warrant requirement.23
Delaware law puts probationers under the supervision of the Department of Corrections, whose probation officers “shall attempt in each case to effect a satisfactory adjustment between the individual and the individual’s needs and the demands of society.”24 By statute, probation officers “may conduct searches of individuals under probation and parole supervision in accordance with Departmental Procedures .... ”25 The purpose of the Department of Corrections’ procedures governing searches of probationers “is to ensure that the Department has sufficient grounds before undertaking a search.”26 We do not require the probation officers to satisfy “each technical requirement of the search regulations” before conducting an administrative search of a probationer.27 Rather, we require only substantial compliance28 because under federal law29 an administra*17tive search of a probationer’s home requires only reasonable grounds.30
There was substantial compliance with Procedure 7.19
Procedure 7.19 of State of Delaware Department of Correction Bureau of Community Corrections Probation and Parole (“Procedure 7.19”) provides the guidelines and procedures for probation officers to apply when making an arrest or search of a probationer,31 and “will be used in the decision-making process for all planned searches” absent exigent circumstances.32 There are five factors calling for a review of the “yes” or “no” responses before conducting an administrative search: (1) whether the probation officer has sufficient reason to believe the offender possesses contraband; (2) whether the probation officer has sufficient reason to believe the offender is in violation of his probation; (3) whether information from a reliable informant indicates that the offender possesses contraband or is violating the law;33 (4) whether information from the informant is corroborated; or (5) whether approval is obtained from the supervisor, manager, or director.34
Procedure 7.19 provides alternative grounds for an administrative search
The majority focuses on the third and fourth factors, which involve the sufficiency of tips (anonymous or otherwise), as dispositive of the “substantially complied” prong of the analysis. We agree with the majority’s analysis that the tip was insufficient under LeGrande.35 Regardless, there still must be consideration of the remainder of the checklist guidelines in Procedure 7.19, which the probation officers testified that they went through in making their decision to conduct an administrative search. According to Robert’s testimony during the suppression hearing, “Any one of those questions answered yes *18establishes sufficiency under 7.19 to conduct an administrative search.”
Procedure 7.19 does not require information from a reliable informant as the sine qua non for a valid administrative search. To the extent that the probation office receives an anonymous tip, this Court’s opinion in LeGrande explains why corroboration of the concealed criminal activity in the tip needs more than just the confirmation of facts tending to identify a determinate person.36 Those requirements do not change when the tip comes indirectly from the police.37
The majority recognizes this point, but further interprets Procedure 7.19 to require police officers to “provide probation officers with sufficient facts so that the probation officers can independently and objectively assess the reasonableness of the inferences to be drawn from the caller’s tip.”38 Nothing in Procedure 7.19 requires this sharing of information and it is unnecessary given the well-established standards for evaluating the credibility of tips. Indeed, the United States Supreme Court’s reasoning for not creating such a requirement is persuasive: “[P]olice may be unwilling to disclose their confidential sources to probation personnel.”39 Further, “[i]n some cases — especially those involving drugs or illegal weapons — the probation agency must be able to act based upon a lesser degree of certainty than the Fourth Amendment would otherwise require in order to intervene before a probationer does damage to himself or society.”40
More importantly, the tip provided to the probation office — which was undisput-edly and conceded by the State as insufficient to generate either reasonable suspicion or probable cause — was but one reason for the administrative search in this case. After concluding that the tip provided here should have resulted in a negative response to the third and fourth factors of Procedure 7.19’s checklist requirement, the majority acknowledges that it still must evaluate the other reasons given by the probation office and whether they provide a reasonable basis for the probation officer to conduct an administrative search. The majority states “[wjithout Lt. Ogden’s call, we must conclude that the probation officers making this inquiry under the Department of Corrections mandated framework for an analysis would not have concluded there was a reasonable basis to conduct this search.”41 We disagree.
An administrative search based upon either drug possession or drug consumption by a probationer stands on its own under either the first and second factors of Procedure 7.19 to justify an administrative search. As conceded by the majority, the officers answered “yes” to these factors and explained that two of the three reasons why they conducted the search were that (1) Culver had failed drug tests during probation and (2) that he had missed *19one curfew. The first reason supports answering “yes” to the first and second factors; the second reason supports answering “yes” to the second factor. Procedure 7.19 authorized an administrative search for either reason notwithstanding the police officer’s “tip” and the majority’s analysis of factors three and four. The officers testified that these were also reasons in addition to the tip that provided a sufficient basis for conducting the search and the Superior Court accepted their testimony. There is no dispute that the search itself was conducted properly. We find no abuse of discretion by Superior Court in concluding that the probation officers substantially complied with the procedural requirements for the administrative search.
The administrative search was reasonable
Even with substantial compliance with Department of Corrections procedures, there still needs to be a reasonable basis to conduct the administrative search to pass constitutional muster.42 A search of a probationer must be reasonable to be constitutionally sufficient.43 “Reasonableness is a flexible concept which must be considered with regard to the totality of the circumstances and with particular regard to the balancing of the needs of effective and reasonable law enforcement with the rights of privacy of the individual.”44 To address how we should review the reasonableness of an administrative search, we need look no further than how reasonableness is measured in every other Fourth Amendment context.
In analyzing the issue under the Fourth Amendment, the reasonableness of a seizure,45 pat down search,46 a warrantless arrest,47 an arrest warrant,48 or search *20warrant,49 the reviewing court does not focus on the subjective motivations or intent of the particular person, but instead makes an objective determination of whether the totality of the circumstances support what is required under the law. Whether it was reasonable for probation officers to conduct an administrative search should be analyzed no differently.
There is no dispute regarding the information within Culver’s file when the probation officers examined it. Culver’s probation started September 5, 2006. His first drug test, administered on September 7 to establish a baseline for his drug levels, tested positive for cocaine (approximately 457 out of a 1000 point scale) and “over 100” for marijuana.50 Roberts testified that results “over 100” indicated that Cul-ver was “smoking in large quantities and usually at approximately a daily rate” and “actively smoking, if not on a daily basis, close to it.” Culver again registered “over 100” on his second drug test, administered on September 28, a result which Roberts testified indicated to her that the marijuana levels in his system “stayed exactly the same.”51 The third drug test was on October 12 and Culver registered at 73. Roberts testified that this result demonstrated Culver was “probably smoking less frequently, but still pretty heavily” and that he was “actively smoking if [the result is] still greater than 50.” On October 14, Culver missed his curfew, and on October 16, the probation office, prompted by the phone call by Lt. Ogden, examined Cul-ver’s file. The record also indicates that there was a fourth drug test which registered “negative,” but a date for this test does not appear in the record. Because the search was on October 16, presumably this test was done during that four-day interval.52
The majority agrees that under the ordinary totality of the circumstances approach, the question facing a trial court (and this Court on appeal) is whether an objective probation officer, examining these facts, would have had a reasonable basis to conduct the search that day. Instead of applying this objective analysis, *21the majority concludes that these officers did not have a reasonable basis to do so because they “would not have searched on October 16, but for Lt. Ogden’s call.” “Subjective intentions play no role in ordinary, probable-cause Fourth Amendment analysis.”53 Nor do subjective intentions play a role under an ordinary Fourth Amendment analysis of an administrative search of a probationer by probation officers.54
In our view, the question is not what these particular officers did or did not choose to do before October 16; the question is whether it would have been reasonable for a probation officer, after examining Culver’s file (and ignoring the tip from the police), to have decided to conduct an administrative search. We find it is objectively reasonable for probation officers to conduct an administrative search of the home of a probationer whose drug tests are positive for more than a month and which show him “actively smoking” just four days before. The subsequent drop from 73 to “negative” in the four-day interval between the third test and the search provides further reasonable support because of the probation officers’ experience with drug detoxification kits. Culver also missed his curfew. The totality of these circumstances provided reasonable grounds to conclude that Culver possessed contraband and was in violation of his probation.
Notwithstanding Culver’s claim that the test results were consistent with the residual effect of past and not current drug use, the trial judge accepted the probation officer’s testimony concerning Culver’s continuing drug use while on probation. Neither Culver nor the majority have demonstrated that these findings were clearly erroneous.55 Accordingly, there was no abuse of discretion in the Superior Court’s denial of Culver’s motion to suppress the evidence seized during the administrative search.56
*22The statements Culver made were admissible
Because we find there was no abuse of discretion in denying the motion to suppress, we must also address Culver’s argument that the Superior Court abused its discretion when it denied his motion to suppress the statements he made to Detective Kline upon the presentment of the warrant for his arrest on the weapon charge. We review the Superior Court’s denial of a motion to suppress after an evidentiary hearing for abuse of discretion.57 To the extent that the claims of error implicate questions of law, our review is de novo.58
Culver argues that the statement should have been suppressed because the officer did not advise Culver of his Miranda59 rights before presenting him with the warrant. The State does not dispute that Culver was in custody, however it argues that the officer did not engage in the functional equivalent of interrogation, so Miranda warnings were not needed. We agree. The trial judge accepted the officer’s testimony and found that his intention was not to question Culver, who made the statement voluntarily and not in response to any question, in order to exculpate himself. Culver’s unforeseeable statement was admissible against him.60 Accordingly, the Superior Court did not abuse its discretion in denying Culver’s motion to suppress this statement.
We find no merit to Culver’s arguments and would affirm the judgment of the Superior Court in all respects. We respectfully dissent.

In this case, the police called and basically said to the probation officers "your probationer is on our radar even though we just conducted a search that turned up empty.” The probation officers then looked at Culver’s file to determine the history of his supervision and whether they had a reasonable basis to conduct an administrative search. Cronin testified that the decision to initiate the search was made by himself and Roberts, and he confirmed that nobody from the State Police had asked them to conduct the search.

While a search is never justified by what is found, we note that a detoxification kit was discovered during the administrative search.

. Culver’s federal constitutional argument— often referred to as the "stalking horse” argument because it asserts that the probation officer is acting as an agent (a "stalking horse”) of the police in order to circumvent the warrant requirement under the ruse of an administrative search — has been rejected as a matter of federal law.
