WWU students help hunt campus predator

Instead of toting his usual backpack full of books across campus on Wednesday, Alec Regimbal carried a Ziplock stuffed with whistles.

Alec is what's called a "Green Coat" -- a group of 18 or so unarmed students who patrol Western Washington University and provide escorts when people don't feel safe.

"We are an extra set of eyes," said Alec. "We are in the places the police can't be all the time."
