Martin knew his life had changed irrevocably. He was standing in a field in Maryland, just north of the DC line, and he was pointing his gun at Charlie Viese's crotch, and trying to reason with him.
Martin is a cop in the D.C. barrio. The barrios were set up to hold all Latinos while the government sorts out which people are legal and which are to be deported. Ten years later and it doesn't look like the barrios and the people in them are going anywhere.
While the barrios have prospered the society at large has become more and more corrupt and lawless. In the foreign press they call the barrios concentration camps. Martin imagines that the rest of the world thinks he works in Auschwitz. Martin likes the barrio. It's the rest of his life that's the problem.
