Found in “Field Trip to the Museum of Human History” by Franny Choi, line 17, ninth stanza

“In place of modern-day accountability practices,/ the institution known as “police” kept order”

The poem explores police brutality through the view of people raised in a society where polices do not exist. Choi only references what replaced the police’s role of law enforcement as “accountability practices”.While vague, it suggests that the system revolves around people holding themselves accountable for their wrongdoings rather than an institution like the police.
