signatures he reviewed] were written by the same person.” Bradley’s erroneous conclusion, appellant continues, itself skewed the warrant application hearing, leading the court to believe there was substantially more evidence of Beard’s involvement in the crimes than actually existed.
But, while in hindsight it is beyond cavil that Neal made a mistake in his representations to Bradley, and while the mistake may have had an impact in the outcome of Bradley’s analysis and the warrant application hearing, neither of these points bears much relevance to our inquiry. Under the Fourth Amendment our inquiry is focused neither on the existence nor the consequence of Neal’s error but on the intention behind it.
Turning to this question, for appellant to demonstrate at least recklessness on Neal’s part there must exist evidence that the officer “ ‘in fact entertained serious doubts as to the truth of his’ allegations ... and [a] factfinder may infer reckless disregard from circumstances evincing ‘obvious reasons to doubt the veracity’ of the allegations.”
United States v. Williams, 737 F.2d 594, 602 (7th Cir.1984) (quoting
St Amant v. Thompson, 390 U.S. 727, 731, 88 S.Ct. 1323, 1325, 20 L.Ed.2d 262 (1968),
cert. denied, 470 U.S. 1003, 105 S.Ct. 1354, 84 L.Ed.2d 377 (1985)). There is, however, no direct evidence in the record suggesting that Neal entertained any doubt about the veracity of his statement concerning the signatures when he made it. And, quite unlike the factual records before this court in eases like
Bruning v. Pixler, 949 F.2d 352 (10th Cir.1991), or
DeLoach v. Bevers, 922 F.2d 618 (10th Cir.1990),
cert. denied, - U.S.-, 112 S.Ct. 65, 116 L.Ed.2d 41 (1991), the facts here present no obvious basis on which to build a case of recklessness by inference.
Appellant does proffer the testimony of an expert, retired police officer R. Jon Foster, to the effect that Neal “had no basis for labeling” at least the bank samples as belonging to Beard. See Appellant’s Appendix at 124. Looking back from our vantage this conclusion seems unassailable, but it, too, does little to illuminate Neal’s intentions while he was conducting his investigation. Like counsel at oral argument, Foster tells us Neal made a mistake, but provides us with no grounds for believing that the mistake was the result of any invidious animus.
Foster’s statement does appear to intimate that if Neal had only investigated the source of the O’Meara and bank handwriting samples more thoroughly he would have discovered his error. And, perhaps this is true, but it does little to rescue appellant’s cause. The failure to investigate a matter fully, to “exhaust every possible lead, interview all potential witnesses, and accumulate overwhelming coiToborative evidence” rarely suggests a knowing or reckless disregard for the truth.

Appellant retorts that, even if Neal’s treatment qf the handwriting samples is not actionable under the Fourth Amendment, Hipp’s misrepresentation in his arrest affidavit of a statement by Darren Carter, manager of the O’Meara dealership, surely must be Carter informed Hipp that Jeffrey Beck had purchased a car from the dealership, yet in his affidavit submitted to the county district judge Hipp substituted Beard’s name for Beck’s.
Hipp’s “misrepresentation” here, however, is hardly troublesome. There is no evidence before us even hinting that Hipp’s substitution of Beard’s name for Beck’s was made with an intentional or reckless disregard for the truth; rather, the facts uniformly suggest that Hipp’s substitution was made with the honest conviction that the Beard was employing Beck’s name as an alias to deiraud the O’Meara dealership. All indications are simply that Hipp thought he could help the warrant-issuing judge avoid confusion by piercing through the perpetrator’s alias and
