Final answer:
Law enforcement procedures ordinarily advise positioning a lone prisoner in the back seat on the passenger side when transported by a single officer without a partition for safety and observation purposes.
Step-by-step explanation:
The question "Transporting a prisoner with one officer and no barricade, where do you position the prisoner?" pertains to law enforcement protocols. It is not explicitly detailed in your provided excerpts, which seem to be from a literary work. However, standard procedures recommend that a lone officer should position a prisoner in the back seat, on the passenger side, to allow the officer to observe the prisoner through the rear-view mirror without needing to turn around. This is done for officer safety and to prevent any possible attacks from the prisoner.
In the typical scenario involving transportation of a prisoner with a single officer and without a partition, it is crucial to take necessary precautions. These precautions may include handcuffing the prisoner's hands in front of their body to allow seatbelt use, which is recommended by safety guidelines. Still, each department may have specific protocols based on the situation or available resources.
