Employees, volunteers and school police will patrol near an estimated 100 campuses and set up so-called “safe zones” in neighborhoods that have a high population of Latinos.

A group of teachers, in collaboration with the community organization Union del Barrio, is launching "teacher patrols" to protect students from potential ICE raids.

Officials and volunteers patrolled areas around schools, part of an effort to warn families about potential raids and reassure them that their children were safe at school.
