with the present case where the report is founded on extensive physical evidence gathered by unbiased officers.
In addition to her argument regarding the admissibility of the police report, Dortch contends that Officer Beauford should not have been allowed to testify as an expert witness. Dortch, however, failed to preserve this argument for appeal. Before trial, Dortch filed a motion in limine to exclude Officer Beauford’s opinion testimony, but the district court did not resolve the issue in its written order, instead deferring the matter until trial. During the trial, Officer Beauford testified about his extensive background in accident reconstruction and offered, without objection, an opinion about who caused the accident.
Dortch was free to renew her objection to the officer’s opinion testimony by contesting Officer Beauford’s qualifications at trial, but she failed to do so. “It is well settled that this court will not consider an error or issue which could have been raised below but was not.” Raft v. Comm’r, 147 Fed.Appx. 458, 462 (6th Cir.2005); United States v. Kimball, 194 Fed.Appx. 373, 376 (6th Cir.2006) (holding that although a motion to exclude evidence “was made in limine[,] it is not properly before us because there was no contemporaneous objection made at trial to preserve it for appeal”).
In sum, the district court did not abuse its discretion by admitting Officer Beau-ford’s accident report. The court acted appropriately by admitting the report under Rule 803(8) and allowing Dortch to challenge the substance of the report via cross-examination. Dortch also waived any challenge to Office Beauford’s opinion testimony.
C. Negligent-supervision-and-retention claim against Con-Way
Dortch’s final two arguments affect only her negligent-supervision-and-retention claim. Specifically, she alleges that the district court wrongly limited discovery on this claim, preventing her from obtaining information about all of the previous accidents occasioned by Fowler while driving for Con-Way. She also contends that the district court incorrectly granted Con-Way summary judgment on the claim.
We have no need, however, to address these arguments. As Con-Way explains, and as Dortch concedes, a claim of negligent supervision and retention against an employer can succeed only if the conduct of the employee in question injured the plaintiff. See Airdrie Stud, Inc. v. Reed, No.2001-CA-001397-MR, 2003 WL 22796469, at *2 (Ky.Ct.App. Nov.26, 2003) (“An employer cannot be liable for negligent retention unless the employee committed a negligent or intentional act resulting in injury to the plaintiff.”); see also Guthrie v. Conroy, 152 N.C.App. 15, 567 S.E.2d 403, 411 (2002) (holding that “[absent a viable tort claim against” an employee, the plaintiff “cannot maintain an action against [the employer] for negligent retention and supervision”); Mulhern v. City of Scottsdale, 165 Ariz. 395, 799 P.2d 15, 18 (Ct.App.1990) (“[T]he employer is not negligent in hiring or retaining the employee as a matter of law if the theory of the employee’s underlying negligence fails.”).
Put another way, Con-Way could be liable to Dortch for negligently supervising and retaining Fowler only if Fowler caused the traffic accident in question. But none of Dortch’s arguments on appeal invalidate the jury’s verdict in favor of Fowler and Con-Way on the underlying negligence claim. Because we have found no reversible error in the conduct of the trial, and because the jury found that Fowler was not negligent, the issue of whether the
