Nothing in "Border patrol" tells us which border is meant, which country is on either side, or who is being stopped. That blankness is deliberate, and it makes the poem feel less like reportage than like a diagram of how a certain kind of power works. Its subject is what happens to a person, and to that person's account of themselves, when they stand in front of an institution that decides what counts as "foreign."
The first line sets the terms: "hours without a witness." Everything that follows happens unobserved, in time nobody is recording. Then comes the institutional voice, flat and procedural: "the state and Customs / assess the foreign." "Assess" is a clerk's verb, and "the foreign" is an abstraction that turns a human being into a category. It is also the only place in the poem where a capital letter appears. Everything else is lowercase, without a full stop in sight, so "Customs" stands up out of the text as the one thing granted official dignity.
The next stanza turns darker through a pun. "Divide and excise" brings together two meanings of the second word: a tax levied on goods, and the surgical act of cutting something out. "Part by part" then pushes the idea toward dismemberment, as if the border were a machine for taking things, and perhaps people, to pieces. The "divide" of "divide and conquer" lurks behind the phrase, though the poem never says so.
Then the poem does something unexpected and swerves into a crow. The "prerogative of the crow / to take any sandwich / with a cheap cry and fright" is the most vivid image here, and a quietly comic one. A prerogative is a lordly word, a privilege of kings, and the poem hands it to a scavenger bird snatching lunch. The comparison deflates the officials while making them more menacing. Their power may be petty, but it is also arbitrary. They can take "any" sandwich, the most ordinary of possessions, and the "cheap cry" suggests a show of noise and bluster that does the frightening work. It also recalls the familiar sight of food being confiscated at crossings, though the poem leaves that connection for the reader to make.
The fourth stanza changes pronoun: "they kill a story / like a dissembling fanatic." Until now the actors were abstract institutions, but "they" puts agents on the scene. What they kill is a story, the traveller's own account, and that loss links back to the opening, since without a witness there is nobody to tell it differently. The simile is strange. A "dissembling fanatic" is someone who hides real conviction behind a calm face, and the comparison suggests an official who looks neutral while carrying out something closer to zeal.
The ending is the poem's most open moment: "laugh to hear pound / the greatest heart." The grammar is loose enough to allow several readings. "Pound" might be a verb, so we are told to laugh at the sound of a heart hammering in fear. It might be money, the currency that Customs ultimately guards. The line could even be a bitter joke at the expense of those who find a frightened pulse funny. Whether the laughter belongs to the officials or is a defiant laugh from the one detained, the poem doesn't settle it. What survives the dismantling is the body's own noise, the heart that goes on pounding after the story has been killed.
The poem's shape supports this. It has no rhyme and no regular metre, only short, clipped lines in stanzas of three or two. The line breaks often leave a phrase dangling, as with "Customs" at the end of a line, waiting for its verb. The hard consonants ("cheap cry," "kill a story," "part by part") make the speech sound like something being chopped up.
The poem is significant for how much it does in so little space. It makes no speeches and names no villain. Through a pun, a bird, and a single capital letter, it shows how bureaucratic language can dress up cutting and taking as routine "assessment," and it leaves us listening to the one sound that paperwork can't absorb.
