Two more mass shootings begin America's week

Five people were shot and one has died from a mass shooting at a Christian retreat in California and a father killed his daughter and three other relatives before killing himself in Alabama.

These shootings have begun another American week of mass violence that have marred the national landscape from coast to coast since mid-March.

So far, there has been little national response to the growing epidemic. What will it take and how many more people have to die?
