Between the lines: Facial recognition debate coming to schools nationwide

Between the lines: Think of the fights over closed-circuit surveillance cameras, school resource officers, and metal detectors. Any change, even for safety, is going to come with major controversy — along with uneven application for schools with more poor and minority students.

• Flashback: Marjory Stoneman Douglas student and activist David Hogg told Axios in March that school "is a prison now" because of increased security measures for students.

What they're saying: Advocates for the tech say its system — matching a face to people banned from the premises — would have helped identify shooters like Nikolas Cruz as soon as they entered school grounds.

• The other side: "Jennifer Lynch, senior staff attorney with the Electronic Frontier Foundation, a digital rights group, said any school considering facial recognition must consider who will have access to data, how such a system would be managed and whether students can opt out."
