Want to help fight human trafficking? A new app for iPhones, Android phones, and Blackberry phones —iFreedom! (with the exclamation mark)—allows you easily to identify and report suspicious behavior. Here is the  Apple store link to Freedom! for iPhone. 

This is a video link that takes you to info about the organization that created the Freedom! app. The founder is a former FBI agent who shares good info, even if you don't get the app.
