PHOENIX (AP) -- New Jersey Gov. Chris Christie says law enforcement, religious groups and public shame can work together to prevent human trafficking at major events like the Super Bowl.Christie said Friday in an event with Cindy McCain, the wife of Arizona Sen. John McCain, that the trafficking of immigrant men and women "absolutely ruins lives."He says it can be difficult to address because victims are often untrusting of law enforcement.Christie says religious groups like the Catholic Church have helped victims in New Jersey and public shame can often discourage the use of websites to promote the activity.Police say sex trafficking tends to spike as women forced into prostitution flock to sporting events. New Jersey is hosting the 2014 Super Bowl and Arizona holds the event the following year.© 2013 The Associated Press. All rights reserved.
