Final answer:
Marty Grimsley is viewed as an imprudent robber due to his lack of foresight in demanding a check during a bank heist and his attempt to deposit it into his own bank account, which led to his capture.
Step-by-step explanation:
In the story provided, the author likely views Marty Grimsley as d. an imprudent robber. The notion that Marty, with a pistol in hand, demanded not only the cash available but also a check for the remaining amount demonstrates a significant lack of foresight and an impractical approach to crime.
His arrest following the attempt to deposit the check into his own bank account further underlines his imprudence. This scenario reflects a lack of understanding of modern banking systems, wherein most money exists as electronic records, rather than physical currency that can be easily stolen and used.
