NPR has been producing a series of stories this week on youth violence, and included in the mix was the story of Safe Passage. Safe Passage is a federally funded program to ensure safety of students headed home from school, which the article called "one of the most dangerous times of day for teenagers." In a nutshell, the program involves added security officers, law enforcement patrols, even aerial surveillance of hot spots -- all with the goal of making sure the nation's next generation of leaders make it home safely.
Read more about Safe Passage on NPR's site, where they also have published the "Morning Edition" audio segment about this new program.
