In an action against President Obama’s immigration policies, 10 undocumented immigrants were arrested for civil disobedience in front of the gates to the Democratic National Convention yesterday evening. The 10 arrestees were riders on Undocubus, which made its way cross-country to Charlotte after leaving from Phoenix more than a month ago. After their arrest, immigration authorities questioned them in jail–but following an all-night call-in and petition campaign, all 10 were released this morning. I boarded Undocubus last week in Knoxville, Tennessee, and rode through the South to Charlotte, North Carolina to report for Colorlines.com and The Nation. In this reporter’s notebook, I document what it’s like to witness a modern-day ride for freedom and justice.
