reasonably foreseeable conduct of others in furtherance of that criminal activity, are not necessarily identical. For example, two defendants agree to commit a robbery and, during the course of that robbery, the first defendant assaults and injures a victim. The second defendant is accountable for the assault and injury to the victim (even if the second defendant had not agreed to the assault and had cautioned the first defendant to be careful not to hurt anyone) because the assaultive conduct was in furtherance of the jointly undertaken criminal activity (the robbery) and was reasonably foreseeable in connection with that criminal activity (given the nature of the offense).
With respect to offenses involving contraband (including controlled substances), the defendant is accountable for all quantities of contraband with which he was directly involved and, in the case of a jointly undertaken criminal activity, all reasonably foreseeable quantities of contraband that were within the scope of the criminal activity that he jointly undertook.
The requirement of reasonable foreseeability applies only in respect to the conduct (i.e., acts and omissions) of others under subsection (a)(1)(B). It does not apply to conduct that the defendant personally undertakes, aids, abets, counsels, commands, induces, procures, or willfully causes; such conduct is addressed under subsection (a)(1)(A).
A defendant’s relevant conduct does not include the conduct of members of a conspiracy prior to the defendant joining the conspiracy, even if the defendant knows of that conduct (e.g., in the case of a defendant who joins an ongoing drug distribution conspiracy knowing that it had been selling two kilograms of cocaine per week, the cocaine sold prior to the defendant joining the conspiracy is not included as relevant conduct in determining the defendant’s offense level). The Commission does not foreclose the possibility that there may be some unusual set of circumstances in which the exclusion of such conduct may not adequately reflect the defendant’s culpability; in such a case, an upward departure may be warranted.
Illustrations of Conduct for Which the Defendant is Accountable
(a) Acts and omissions aided or abetted by the defendant
(1) Defendant A is one of ten persons hired by Defendant B to off-load a ship containing marihuana. The off-loading of the ship is interrupted by law enforcement officers and one ton of marihuana is seized (the amount on the ship as well as the amount off-loaded). Defendant A and the other off-loaders are arrested and convicted of importation of marihuana. Regardless of the number of bales he personally unloaded, Defendant A is accountable for the entire oneton quantity of marihuana. Defendant A aided and abetted the off-loading of the entire shipment of marihuana by directly participating in the off-loading of that shipment (i.e., the specific objective of the criminal activity he joined was the off-loading of the entire shipment). Therefore, he is accountable for the entire shipment under subsection (a)(1)(A) without regard to the issue of reasonable foreseeability. This is conceptually similar to the case of a defendant who transports a suitcase knowing that it contains a controlled substance and, therefore, is accountable for the controlled substance in the suitcase regardless of his knowledge or lack of knowledge of the actual type or amount of that controlled substance.
In certain cases, a defendant may be accountable for particular conduct under
