73-Year-Old Librarian Shot & Killed By Police… During A 'Shoot/Don't Shoot' Community Training Exercise!

This is one of the most tragically needless deaths we've ever heard of.
A 73-year-old woman was just shot and killed by police on Tuesday night during a training exercise aimed at showing how difficult it is for cops to know when to shoot.
Apparently, Mary Knowlton was participating in a "shoot/don't shoot" community event in Punta Gorda, Florida when she was randomly selected to pretend to be a bad guy facing off against police.
