In today's Estela's Escuelas: keeping children safe while they're surfing the web. Today Homeland Security Investigators with special agents from the U.S. Immigration and Customs Enforcement, launched a new project call "I-Guardian". This is video of them setting up for the event at Horizon Heights. The goal of the project is for children to "think before they click". H.S.I. used super-hero style characters and trading cards that were developed for the project to help teach kids about safety online.
