Students say it's not an option to leave their phones at home. They depend on them for security as they travel through scary, opioid-infested neighborhoods to get to and from school (and you can't tell me that Kensington High's own staffers don't do the same). They also use them to text their parents, to let them know they've arrived safely at a part-time job or have picked up a sibling from an after-school program.
