Phoenix activists Lydia Guzman and Todd Landfried hope to design a phone app for immigrants ensnared by the rash of recent immigration laws that have swept the nation. The app would alert family, lawyers and social media outlets of the stop, detention or arrest. I wrote about the SOS phone app for immigrants and, as Landried told me, anyone who looks like an immigrant. You may recognize Guzman’s name — she’s a longtime activist who designed a phone texting system that responded to Sheriff Joe’s raids, back in the day before he had his wings clipped by DHS and DOJ. Landfried works for Arizona Employers for Immigration Reform, and travels across the country speaking about the economic pitfalls of harsh immigration laws.
