Heading: Expert Testimony Regarding Distribution Amounts of Crack Cocaine

Text: 14 During the testimony of Detective Herrera, an expert witness regarding street sales, distribution, and use of crack cocaine in the Denver or Aurora area, defendant objected to Herrera giving his opinion regarding the amount of crack that indicates distribution rather than mere personal usage. We review the trial court's decision to admit or exclude expert testimony for abuse of discretion, see United States v. Markum, 4 F.3d 891, 895 (10th Cir.1993); United States v. McDonald, 933 F.2d 1519, 1522 (10th Cir.1991), and find none here. Detective Herrera made a general observation and did not cross the line of making a determination that should be left to the jury. He did not offer an opinion regarding the cocaine purchased specifically by Mr. Locke. 15
