Could a grass roots movement change America's permissive gun laws in the wake of the massacre of six- and seven-year-olds?
It happened thirty years ago, when a grieving mother named Candy Lightner turned her anguish into action and created Mothers Against Drunk Driving, or “MADD”.
She did that in 1980, just days after she buried her 13-year-old daughter Cari. MADD’s first office was Cari's bedroom.
From there she launched a movement that changed the way Americans and America’s laws treat drunk driving. And it soon spread to the rest of the world. MADD now has 600 chapters in all fifty states.
Since 1991, drunk driving deaths have been cut by almost 40%. And for the first time on record, the number of alcohol-related traffic deaths dipped below ten thousand.
The loss of one child helped change America’s drinking culture.
Will the loss of twenty young lives mark a sea change when it comes to tolerating military style weapons on America's streets?
