What does greater probe spread likely increase the likelihood of?

Greater probe spread increases the effectiveness of the Taser by maximizing the chances that the electrical charge will impact critical muscle groups, which is essential for incapacitating a subject. This increased spread of the probes allows for a more effective deployment of the electrical charge across the body, leading to neuromuscular incapacitation (NMI). NMI refers to the temporary disruption of the body's ability to function normally, allowing law enforcement to gain control of a potentially dangerous situation without causing permanent harm.

While localized pain, cardiac arrest, and hallucinations are concerns related to electrical weapons, they are not directly tied to the aspect of probe spread. Localized pain could occur if the probes are penetrated into a smaller area but does not represent the primary function of greater probe spread. Similarly, cardiac arrest is a serious risk associated with electrical shocks but is not inherently influenced by the distance between probes. Hallucinations are not a recognized effect of Taser use and have no direct correlation in this context. Thus, emphasizing the connection between probe spread and the likelihood of achieving NMI clarifies why that choice is the most appropriate.
