What is ricin primarily associated with, regarding potential attacks?

Ricin is a highly toxic compound derived from the castor bean and is primarily associated with mail and delivery attacks. The reason for this association lies in the simplicity of its production and the ease with which it can be concealed in common mail items. Past incidents have demonstrated that ricin can be effectively delivered to intended victims through letters or packages, making it a favorable choice for individuals looking to utilize chemical agents in targeted attacks.

This delivery method allows for a level of anonymity and the potential for widespread harm, particularly if the substance is adequately contained to avoid detection during transit. Additionally, it minimizes the risk to the attacker, as they do not need to be present at the site of exposure.

While air supply contamination, explosive devices, and public poisonings in food supplies are significant threats associated with other chemicals or methods of attack, they do not specifically align with the historical and practical uses of ricin as observed in prior cases, thus reinforcing the link between ricin and mail-related incidents.
