ESCHBACH, Senior Circuit Judge.
Randall W. Sutherland was convicted of conspiring to commit mail fraud on war veterans and their families. To perpetrate his fraud, he represented himself as a military historian, author, publisher, and physician who needed to borrow veterans’ memorabilia to write a book. R. 34. Beginning in mid-1988, Sutherland obtained membership rosters of veterans’ organizations, solicited war memorabilia from veterans and their widows, and then sold the memorabilia for his personal gain. He never wrote any book or returned any of the items, as promised. During the proceedings below, Sutherland agreed to plead guilty to the crime in exchange for the government’s recommendation that he receive a sentence at the lower end of the range specified by the sentencing guidelines, as well as a two-level reduction for acceptance of responsibility. R. 34. In addition, the Springfield probation officer recommended a sentence of 15 months. Despite the government and probation officer’s recommendations, the district court imposed the maximal sentence on Sutherland, 16 months of imprisonment, including a two-point upward adjustment for having preyed on “vulnerable victims.” Sutherland appeals that adjustment.
§ 3A1.1 of the United States Sentencing Guidelines provides that “If the defendant knew or should have known that a victim of the offense was unusually vulnerable due to age, physical or mental condition, or that a victim was otherwise particularly susceptible to the criminal conduct, increase by 2 levels.” Whether a defendant’s victims were “unusually vulnerable” is a question of fact reversible only for clear error. United States v. Creech, 913 F.2d 780, 782 (10th Cir.1990). The district court decided that Sutherland’s victims, World War I and II veterans and their families, were unusually vulnerable because of their age and their status as war veterans. The court 1) calculated that World War I veterans would have been in their eighties when Sutherland contacted them, and World War II veterans would have been in their sixties or older. Tr. at 11. Then the court 2) stated a “truism that this Court can take judicial notice of.... We tend to place greater emphasis as we get older upon those high points and mountain top experiences of our lives and recall with more reminiscence what took place and things become more significant to us.” Tr. at 11-12. Based on this “truism,” the district court 3) took the further step of concluding that war veterans would be unusually susceptible to a fraud based on collecting and converting their personal war memorabilia.
We do not believe that the district court heard sufficient evidence to support either of the first two steps it took in concluding that the veterans were vulnerable victims. In a fraud ease where the defendant issues an appeal to a broad group, the court should focus on whom the defendant targets, not on whom his solicitation happens to defraud. See United States v. Wilson, 913 F.2d 136, 138 (4th Cir.1990); cf. United States v. Cree, 915 F.2d 352, 354 (8th Cir.1990) (defendant’s involuntary manslaughter sentence could not be enhanced for victim vulnerability because in committing an involuntary crime, defendant did not target anyone). The notes to § 3A1.1 illustrate this rule, stating that the vulnerable victim adjustment “would not apply in a case where the defendant sold fraudulent securities by mail to the general public and one of the victims happened to be senile” (emphasis added). The rule makes sense. § 3A1.1 is designed to punish criminals who choose vulnerable victims, not criminals who target a broad group which may include some vulnerable persons.
In the present case, the district court concluded that Sutherland’s victims were vulnerable largely because of their age. Granted, Sutherland “primarily targeted World War II veterans or their widows.” But he also contacted Vietnam veterans during his solicitations. Presentence Report at 2. Some of his solicitations were published in a general magazine with a national circulation. Tr. at 9-10. And Sutherland contacted veterans’ widows, Presentence Report at 2, whose life experi-
