Oregon’s largest school district said Thursday it will discontinue the use of school resource officers in its schools in the aftermath of the death of George Floyd.

The announcement makes it one of a handful of districts from Minneapolis to Denver that are taking a closer look at the role the police officers play in their schools.

Superintendent Guadalupe Guerrero said on Twitter that Portland Public Schools needed to “re-examine our relationship” with the police in light of the national outrage over the death of George Floyd, who died after a white Minneapolis police officer pressed his knee into Floyd’s neck for nearly nine minutes.
