The Fourth Amendment aims to strike a balance between the fundamental right to be free from unreasonable searches and seizures and allowing law enforcement officers to take effective action to protect the public interest.2 Yet, because the standard for effecting warrantless arrests relies on a nebulous “totality of the circumstances” analysis,3 exactly what information a police officer must consider before effecting such an arrest is unclear. While much of the probable cause calculation is settled law at this point4, it remains undecided whether an officer must have probable cause for every element of a crime, including mens rea, and how much attention officers must pay to evidence tending to negate that mens rea. Ultimately, this Contribution will argue that in order to effect a warrantless arrest a police officer must have probable cause with respect to every element of the crime in order to effect a warrantless arrest and must not ignore exonerating evidence in their totality of the circumstances analysis.

Precedent is clear that, in order to make a valid arrest without a warrant, the arresting officer must analyze probable cause at least as stringently as the warrant process would5 since an arrest without a warrant “bypasses the safeguards provided by an objective predetermination of probable cause.”6 To meet this requirement, the officer is required to consider the “totality of the circumstances,” a standard first instituted by the United States Supreme Court in Illinois v. Gates to determine whether probable cause existed to search a house.7 The Court emphasized that the totality of the circumstances analysis was meant to be a “commonsense, practical” analysis.8
Yet case law is often unclear as to what information must be considered in the totality of the circumstances analysis and what officers must have probable cause of in order to arrest a person. Prior to Illinois v. Gates, the Supreme Court held that a warrantless arrest was unconstitutional absent “information hinting further at the knowledge and intent required as elements of the felony under the statute.”9 In United States v. Di Re, the officer made an arrest because he saw illegal gambling coupons in a car, but the Court noted that presence alone did not speak to the knowledge and intent requirements of the statute.10 Yet, subsequently in Maryland v. Pringle, where multiple men were found in a car with controlled substances, the Court permitted the arresting officers to infer the knowledge mens rea for each individual11 While officers need not have trial-level proof of every element of the crime at the moment of arrest,12 the Pringle and Di Re decisions indicate that mens rea must play a part in the totality of the circumstances analysis in some way. The remaining question is whether officers must have specific facts indicating the requisite mens rea or whether a mere inference will always suffice.
Though Pringle seemed to suggest that an inference is sufficient, circuit courts have split on the issue. The Fourth, Seventh, and Ninth Circuits hold that an officer need not establish probable cause for each element of an offense,13 while the Third, Sixth, Eighth, and D.C. Circuits hold that probable cause must extend to every element of an offense.14 One of the earliest cases to adopt the understanding of probable cause as not requiring probable cause for every element, United States v. Sevier, focused on the idea that probable cause should be practical and nontechnical.15 But as the Eighth Circuit said, “[f]or probable cause to exist, there must be probable cause for all elements of the crime, including mens rea.”16
By its very nature, the totality of the circumstances test requires an officer to consider all circumstances related to a possible crime. A number of the circuit courts have emphasized that law enforcement cannot ignore or disregard exculpatory facts in their probable cause analysis.17 Necessarily, the totality of the circumstances analysis, while providing that law enforcement officers can look at the entirety of the circumstances surrounding the alleged crime, also requires that they consider facts tending to dissipate probable cause.18 To hold otherwise would render probable cause analysis a nullity, because officers could claim probable cause despite significant facts to the contrary.
It is a necessary aspect of the totality of the circumstances analysis that “police officers may not ignore easily accessible evidence and thereby delegate their duty to investigate and make an independent probable cause determination based on that investigation.”19 The probable cause inquiry “requires officers to reasonably interview witnesses readily available at the scene, investigate basic evidence, or otherwise inquire if a crime has been committed at all before invoking the power of a warrantless arrest and detention.”20 Failure to investigate exculpatory or other information prior to arrest can prevent the establishment of probable cause.21
In BeVier v. Hucal, the Seventh Circuit held that an arrest was not valid without evidence of the requisite mens rea and that an officer’s decision to ignore information tending to negate mens rea opened him up to a valid § 1983 claim.22 The Seventh Circuit does not require probable cause of every element of the crime23 yet still prohibits officers from ignoring exculpatory evidence on the subject of mens rea. And circuits on both sides of the split agree that it is in keeping with law enforcement’s duty to examine the totality of the circumstances that officers may not close their eyes to facts that would clarify the circumstances of an arrest, particularly where it is unclear whether a crime had taken place or where further investigation may exonerate the suspect.24 While law enforcement need not have proof beyond a reasonable doubt at the time of arrest,25 they must at least conduct a reasonably thorough investigation where there are no exigent circumstances26 or where minimal, reasonable further investigation would shed light on the events.27 This logic demonstrates that the workable solution to questions of mens rea at the moment of arrest is to return to a more robust understanding of the totality of the circumstances analysis that focuses on the actual totality, both exculpatory and inculpatory.

Advocates of not requiring probable cause for mens rea argue that asking officers to look into the state of mind would frustrate legitimate law enforcement purposes.28 However, under the probable cause of mens rea standard, officers need not peer into suspects’ minds in order to ascertain their mental state at the time of a possible crime. While officers cannot know what a suspect’s exact state of mind is, they also may not ignore evidence suggesting a suspect lacks the requisite mens rea. For most crimes, a guilty mens rea is what makes otherwise innocent behavior into criminal action. Without evidence of that mens rea, criminal suspects risk having their lives disrupted by court proceedings or pre-trial detention despite having engaged in behavior not specifically criminalized by the statute.
Evidence tending to support or negate the existence of the requisite mens rea is often readily available at the time of arrest. As a start, criminal suspects may make statements either inculpating or exculpating themselves. Yet officers do not have to just take suspects at their words.29 As was the case in Maryland v. Pringle, officers make inferences about whether knowledge or intent existed by, for example, looking at how visible the illicit substances were or how obvious the criminal behavior was.30 The key point here is that officers must not only look at evidence that supports the guilty mens rea; the totality of the circumstances analysis necessarily requires them to also examine evidence tending to negate mens rea, just as they must for any other piece of exculpatory or undisputed information.
In order to abide by this proposed standard, law enforcement officers do not need to conduct an exhaustive investigation prior to arrest. Instead, effective and constitutional law enforcement includes learning “what easily could have been learned, and in common prudence should have been,”31 or performing minimal investigation that “would have reduced any suspicion created by the facts police had discovered.”32 Already, law enforcement officers check the Vehicle Identification Number of a car or ask its driver for the vehicle’s registration papers prior to concluding that a car is stolen. It is not unreasonable to ask that an officer similarly ask suspects about the circumstances of the alleged crime or consider information easily produced or readily available at the scene that sheds light on a suspect’s state of mind. That basic level of inquiry would satisfy the proposed inquiry into the suspect’s mens rea.

An understanding of the totality of the circumstances analysis that considers both inculpatory and exculpatory information with regards to the suspect’s mens rea and requires minimal investigation in unclear circumstances bridges the gap between the inability of law enforcement officers to read the minds of criminal suspects and the right of people to be free from unreasonable arrests. By doing so, it still allows law enforcement to do their jobs quickly and on the scene but prevents wrongful arrests and the many consequences that can accompany such unlawful arrests. In the compromise between these important interests, requiring law enforcement officers to examine the true totality of the circumstances strikes the right balance.

This piece is a commentary on a problem written for the 2017 Herbert Wechsler National Criminal Moot Court Competition at the University of Buffalo School of Law.
