Note that this ranger is female, just like the Border Patrol officer who let Tacho and Rigoberto into the US. By including these female characters as part of the landscape, the novel shows that women can absolutely hold positions of power. This implies that the women of Tres Camarones don’t actually need men to protect the village. Meanwhile, the Kansas cop’s rude comment about “illegals” shows his racism. Although Tacho and Nayeli
are illegal immigrants, the cop seems to think the very fact that they are Mexican means that they must be illegal immigrants. In addition, by calling Tacho and Nayeli “illegals” rather than people, the cop dehumanizes them.
