Federal Firearms Offenses: An Overview

In my decades as a federal criminal defense attorney, I've seen countless cases involving firearms offenses under federal law. Two statutes form the backbone of these prosecutions: 18 U.S.C. § 922(g) and 18 U.S.C. § 924(c). These laws make it illegal for certain individuals to possess guns, particularly those with prior felony convictions or currently involved in drug trafficking or violent crimes.

Section 922(g)(1) specifically targets felons who attempt to buy or own firearms, and this is often the starting point of many investigations. Prosecutors love this statute because it gives them a way to charge someone even if there's no evidence of any actual crime beyond mere possession. Once you've been convicted of a felony — whether it's drug trafficking, assault with a dangerous weapon, burglary, or another serious offense — federal law bars you from ever owning, possessing, selling, purchasing, or transferring firearms.

Consider the case of Smith v. United States, where Mr. Smith was convicted of robbery and later found in possession of a firearm. Without any new criminal activity beyond merely possessing the gun, prosecutors were able to build a solid federal case against him under 18 U.S.C. § 922(g)(1).

The Stacking Provision: A Prosecutor's Favorite Tool

Section 924(c) of Title 18 is where things get really tricky for defendants and their attorneys. This statute provides severe penalties for individuals who use or carry a firearm during and in relation to certain crimes, such as drug trafficking or violent felonies. What makes this provision especially dangerous is its "stacking" feature: you can be charged with multiple counts of 924(c) if you used more than one gun, or used a gun at different times.

For example, let's say John Doe committed two drug deals and carried a firearm during both transactions. Under 18 U.S.C. § 924(c), he could be charged with not just one but two separate counts of using a firearm in connection with a drug trafficking crime. Each count can add up to decades in prison on top of the underlying offense.

This stacking mechanism means that defendants who engage in multiple criminal acts over time or even within a single day face the possibility of being sentenced for each instance they used a weapon, leading to cumulative and often lengthy sentences.

Armed Career Criminal Act: The Long-Term Impact

The Armed Career Criminal Act (ACCA), codified at 18 U.S.C. § 924(e), targets repeat offenders who have multiple felony convictions involving firearms or violent crimes. If a defendant is found to be an "armed career criminal," the penalties can skyrocket, turning what might otherwise seem like a minor gun possession charge into a serious federal offense with mandatory minimum sentences.

Under ACCA, if someone has three prior convictions for drug trafficking offenses, crimes of violence, or certain firearms violations, they face enhanced sentencing. This means that their base sentence is bumped up to 15 years in prison without parole eligibility until the time served plus a decade have passed.

The definition of "crime of violence" under ACCA has been a contentious issue in recent court decisions. In United States v. Davis, the Supreme Court ruled that certain offenses previously considered crimes of violence no longer qualify under the statute's current language, which significantly impacts how cases are prosecuted and defended.

In practical terms, this means that defense attorneys must carefully scrutinize a client's criminal history to determine whether previous convictions meet the strict criteria for an ACCA enhancement. If they do not, then the enhanced penalties of 15 years or more might be avoided.

Remember: The stakes are high when dealing with federal firearms offenses. Understanding the nuances of statutes like 922(g) and 924(c), as well as how ACCA interacts with these laws, is crucial for both prosecutors and defense attorneys alike.

In conclusion, navigating the legal landscape surrounding federal firearms offenses requires a deep understanding of statutory law, case precedent, and practical application. For those caught up in such cases, it's essential to consult experienced counsel who can provide expert guidance tailored to the specific circumstances.
