Appeal from the United States District Court for the Northern District of Indiana, South Bend Division. No. 06 CR 105-Allen Sharp, Judge.
The opinion of the court was delivered by: Sykes, Circuit Judge
Before EASTERBROOK, Chief Judge, and ROVNER and SYKES, Circuit Judges.
When the government introduces a defendant's confession to supplement an otherwise legally inadequate case, the Supreme Court requires corroborating evidence to show that the confession is trustworthy. See Opper v. United States,348 U.S. 84, 89 (1954). This "corroboration rule" is at the center of this case.
Germaine Dalhouse was convicted of carrying a gun while being an illegal-drug user. See 18 U.S.C. § 922(g)(3).
He claims the government was wrongly allowed to present his confession to the jury without first producing corroborating evidence that it was trustworthy. We disagree and affirm his conviction. The corroboration rule is satisfied if the government presents enough evidence independent of the confession to allow a jury to convict. The government did that here, so there was no need for additional corroboration.
Most of the facts are uncontested. Germaine Dalhouse was arrested early one morning by police in Elkhart, Indiana, who subsequently discovered that he was carrying a loaded gun for which he had a permit. He was ultimately released but later admitted to police that he was a habitual marijuana user and that he had both carried the gun and smoked marijuana the day he was arrested. Based in part on these statements, Dalhouse was indicted, tried, and convicted for possessing a gun while being an illegal-drug user. See 18 U.S.C. § 922(g)(3).
Dalhouse didn't seriously contest two of the three elements of the crime: that he carried a gun and that the gun crossed state lines. The main issue at trial was the third element: whether he was "an unlawful user of or addicted to any controlled substance" when he possessed the gun. Id. On that element the government offered two pieces of evidence. First was the testimony of Christopher "Wing Ding" King, a friend of Dalhouse who was present when he was arrested. King, who is now serving a 40-year state-prison sentence for dealing cocaine, testified that he had smoked marijuana with Dalhouse only minutes before Dalhouse was arrested. King also testified that he had known Dalhouse for about two and a half months, would see him about every other day, and would smoke marijuana with him whenever they were together. The second piece of evidence was the videotape of Dalhouse's confession, which was played for the jury. In his confession Dalhouse admitted to daily marijuana use "since high school," admitted to smoking marijuana the day of his arrest, and admitted to carrying a gun the day he was arrested.
Dalhouse's attorney argued to the jury that "Wing Ding" King was a liar and pointed to contradictions between Dalhouse's confession and King's testimony. But his primary trial strategy was to try to keep Dalhouse's confession out of evidence. He argued to the district court that the confession could be admitted only if it was sufficiently corroborated by other evidence, which he claimed was lacking. The court rejected this argument, noting there was ample evidence apart from Dalhouse's confession to send the case-with the confession-to the jury. The jury returned a verdict of guilty. Dalhouse was sentenced and now appeals.
The sole issue on appeal is the applicability of the "corroboration rule," a common-law principle that was developed to prevent the government from relying too heavily on confessions, which were once thought to be unreliable. See generally 2A CHARLES ALAN WRIGHT, FEDERAL PRACTICE AND PROCEDURE § 414 & n.33 (3d ed. 2000); 1 MCCORMICK ON EVIDENCE § 145 & n.28 (Kenneth S. Broun ed., 6th ed. 2006). The rule-which is premised on the idea that the pressure of criminal investigations may lead suspects to falsely confess to crimes that never occurred-forbids the government from obtaining a conviction by relying solely on a defendant's confession. What is needed is proof in addition to the defendant's admissions-corroborating evidence-to show that the confession is trustworthy.
The required level of corroboration depends on the government's case. Sometimes the government uses a defendant's admissions to bolster a case that is already legally adequate. When that happens, no additional corroboration is necessary. See United States v. Calderon, 348 U.S. 160, 167 (1954). There is independent evidence of the defendant's guilt and therefore no danger that the government is relying solely on the defendant's uncorrobo-rated confession to convict. See Smith v. United States, 348 U.S. 147, 156 (1954) (either "independent evidence or corroborated admissions" are sufficient). By contrast, if the government uses the defendant's admissions to prove an element of the crime that can't otherwise be adequately proven, then the defendant's statement must be corroborated. Opper, 348 U.S. at 91. Most commonly, that is accomplished by presenting evidence that a few of its key assertions are true, which is sufficient to show that the statement as a whole is trustworthy. United States v. Trombley, 733 F.2d 35, 37-38 (6th Cir. 1984).
What the rule accomplishes is open to debate. An impressive number of critics have suggested that the rule is unnecessary, particularly given the development of modern constitutional confession law, notably Miranda v. Arizona, 384 U.S. 436 (1966), and the voluntariness requirement, see Jackson v. Denno,378 U.S. 368, 376 (1964), which protect suspects against coercive police interrogations. See, e.g., United States v. Dickerson, 163 F.3d 639, 641 n.2 (D.C. Cir. 1999) (criticizing the corroboration rule and citing other critical scholarship); 1 MCCORMICK ON EVI- DENCE § 145 & n.28 (same). For our purposes the criticism is beside the point because the Supreme Court has adopted the rule for the federal courts and has neither overruled nor curtailed it. 2A CHARLES ALAN WRIGHT, FEDERAL PRACTICE AND PROCEDURE § 414 & nn.38-40. But it is worth clarifying that the rule is designed to serve different purposes than Miranda and the voluntariness requirement. While these doctrines seek to protect suspects from coercive police tactics during custodial interrogations, the corroboration rule is premised on the idea that ...
