In which field does Gattaca occasionally accept candidates with "minor shortcomings" according to the director?

In "Gattaca," the narrative revolves around a society that prioritizes genetic engineering and eugenics, leading to a strict hierarchy based on one's DNA. In this context, the director mentions that law enforcement occasionally accepts candidates with "minor shortcomings." This suggests that, while the other fields emphasized a near-perfect genetic makeup—such as medicine, engineering, and education—law enforcement has slightly more leniency regarding genetic imperfections. This acceptance reflects the notion that not all professions require the same level of genetic superiority, and the role of law enforcement may encompass other qualities, such as integrity, dedication, and skills that are not solely determined by genetics.
