How surveillance tech tracks released immigrants

Countries all over the world use technology to keep track of immigrants released from detention centers. The idea is to allow people to live in communities while their cases are adjudicated.

She told Marketplace’s Nova Safo that even smartphone apps, which can be glitchy, are a challenge for immigrants who are often waiting on asylum claims.
