[Episcopal News Service] Tensions escalated July 29 as Arizona's contentious immigration law went into effect, with both opponents and supporters vowing, "we will not comply."

Protestors wore it on T-shirts and chanted it as a rallying cry during demonstrations outside the office of Maricopa County Sheriff Joe Arpaio in downtown Phoenix, where they marched after attending a 6 a.m. interfaith service at Trinity Episcopal Cathedral. Dozens were arrested after a standoff between demonstrators and police wearing riot gear.

Arpaio, running for re-election, launched "Operation 1070," the 17th crime sweep since 2007 to identify, detain and deport undocumented persons, despite a July 28 federal court ruling barring police officers from checking immigration status during traffic stops, detentions and arrests.

Hundreds of SB1070 opponents began the day in prayer and song, chanting 'Si se puede' (yes we can) as they marched a mile north from a vigil at the state capitol to Trinity Cathedral for the "God is Our Hope" interfaith service of prayer and thanksgiving.
