PHOENIX - A federal judge ruled Friday that the office of America's self-proclaimed toughest sheriff systematically singled out Latinos in its trademark immigration patrols, marking the first finding by a court that the agency racially profiles people.

The 142-page decision by U.S. District Judge Murray Snow in Phoenix backs up allegations that Maricopa County Sheriff Joe Arpaio's critics have made for years that his officers violate the constitutional rights of Latinos in relying on race in their immigration enforcement.

Snow, whose ruling came more than eight months after a seven-day, non-jury trial, also ruled Arpaio's deputies unreasonably prolonged the detentions of people who were pulled over.

They hang over neighborhood signs and even at a door to St. Jude Children's Research Hospital.

"Believe Memphis" is the slogan first printed on giveaway towels for fans in the 2011 playoffs, which they held up instead of waving, trying to will the Grizzlies to victory late in a game against Oklahoma City.

Fans are ready for the latest biggest home game in team history, and the Grizzlies hear all the excitement every time they go outside.
