United States v. Ernest Mallety, 496 F. App'x 984

Mallety and eleven codefendants were indicted for cocaine trafficking from Houston to Pensacola (Jan 2008–Mar 2010).
Mallety was tried separately; several codefendants pleaded guilty and cooperated with the government.
Codefendants testified that Hull and Jones led the operation and used Mallety to transport cocaine; Mallety was paid per kilogram and transported multiple kilograms weekly.
DEA Agent Sonya Bryant testified as an expert about drug terminology and distribution patterns based on extensive training and experience.
Wiretap recordings and transactional conversations were admitted; some terms were explained by Bryant, including numerical references and coded discussions.
Mallety was convicted on three counts; the court imposed 175 months (Count 1), 48 months (Count 2) concurrent, and 60 months (Count 3) consecutive, total 285 months; judgment later challenged for clerical errors.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Bryant's expert testimony on drug terminology was plain error	Mallety contends Bryant invaded jury's role by interpreting the recordings and conspiracy details.	Mallety argues the testimony improperly framed the facts and was more than permissible interpretation.	No plain error; testimony reasonable and supported by volume of evidence.
Sufficiency of the evidence for Count 3 (possession of firearm in furtherance of a drug crime)	Evidence showed Mallety possessed firearms to protect drugs and profits, supporting nexus.	Insufficient nexus between firearm and drug trafficking to sustain conviction.	Evidence, including testimony and recorded statements, established a sufficient nexus.
Clerical error in the written judgment regarding Count 1	Judgment improperly referenced cocaine base and 21 U.S.C. § 841(b)(1)(A)(iii).	No consistent objection; error should be corrected.	Remand to strike cocaine base and § 841(b)(1)(A)(iii) from Count 1; five kilograms/§ 841(b)(1)(A)(ii) remains.
Impact of Agent Bryant's testimony on substantial rights	The testimony could have unduly swayed the jury by providing expert conclusions.	Any error was not plain and did not affect the outcome given other evidence.	Even if problematic, not plain error that affected substantial rights; error, if any, was harmless.
