Heres a remarkable case from the Ohio Supreme Court,     State v. Hoffman, involving an unconstitutional    arrest warrant. The defendant was arrested for a misdemeanor    based on a defective arrest warrant, leading to the discovery    of evidence of murder. The remarkable part is why the arrest    warrant was defective. For at least 17 years, magistrates in    Toledo, Ohio were instructed to issue arrest warrants without    ever actually making a probable cause determination. Officers    would just say that the suspect had committed an offense, and    the magistrates would issue the warrant without ever hearing    the factual basis for that conclusion. Heres the testimony of    the magistrate who issued the arrest warrant in this case:  
      Q. And during your 17 years of swearing in criminal      complaints with requests for arrest warrants, did you know      what probable cause was?      A. No.      Q. Had you ever made a probable cause determination?      A. No.      * * *      Q. Did any of [your] training include making a probable cause      determination?      A. No, it did not.    
    Pretty astonishing, given that the text of the Fourth Amendment    says, no warrants shall issue, but upon probable cause.  
    In the new decision, the Supreme Court of Ohio recognizes the    flagrant constitutional violation but concludes that the    evidence in this case should not be suppressed because of the    good-faith exception. An intermediate state case,     State v. Overton, had involved a similar warrant,    and the Overton court had held in a one-paragraph    summary that the warrant had established probable cause. The    Ohio Supreme Court concludes in Hoffman that    Overton was binding appellate precedent under    Davis at the time the warrant was issued in    Hoffman, essentially trumping the text of the Fourth    Amendment for purposes of the exclusionary rule.  
    I find Hoffman puzzling in two ways. First, I think    the scope of the exclusionary rule for a defective warrant is    set by United States v. Leon, 468 U.S. 897 (1984), not    Davis. Leon lays out the standards for when    the good faith exception applies to defective warrants, and it    clearly does not apply here: Leon says that the good    faith exception only applies if [s]ufficient information [was]    presented to the magistrate to allow that official to determine    probable cause; his action cannot be a mere ratification of the    bare conclusions of others. This case involves exactly that    mere ratification that Leon says wont suffice. Given    the clarity of Leon on this point, coming straight    from the U.S. Supreme Court, it seems strange to me to apply    Davis instead based on the conclusory decision in    Overton.  
    Second, even if Leon applies instead of    Davis, its not obvious to me that suppression is an    available remedy. The problem, it seems to me, is that arrests    generally dont require warrants. Unlike searches, they    generally require only probable cause. Given that, its not    clear to me that a defective arrest warrant makes a difference.    If the police have probable cause, they could make the arrest    without a warrant. In such circumstances, I dont see how the    arrest violates the Fourth Amendment (as compared to the    warrant) if the police also obtain a warrant that is defective.    Probable cause authorizes the arrest, not the warrant, so a    search incident to arrest should be okay. Granted, in    Hoffman, its not clear that the police actually had    probable cause. It looks like the officers relied mostly on the    warrant in the suppression hearing rather than making the case    for probable cause directly. Either way, probable cause is the    real issue.
