Gun control groups decry Boulder shooting
The Colorado chapters of Moms Demand Action and Students Demand Action denounced the Boulder shooting. Both are part of Everytown for Gun Safety, which calls itself the largest gun violence prevention organization in the country.
That group's president, John Feinblatt, called it "absolutely heartbreaking."
"This is yet another in a long string of horrific tragedies, from Boulder today to Atlanta last week to the dozens more people in the United States who are shot every day, but whose stories do not make the headlines," he said. "To save lives and end these senseless killings, we need more than thoughts and prayers — we need federal action on gun safety from the Senate and the administration, and we need it now."
Shannon Watts, founder of Moms Demand Action said, "We can't and won't accept gun violence in our supermarkets to spas to our homes, as just another fact of life. It's past time for our leaders to act and protect us from gun violence."
And Colorado Moms Demand Action volunteer Nicole LiaBraaten called it "yet another painful reminder of our nation's urgent gun violence crisis. We should not have to fear for our lives doing something as simple as going to the grocery store. We must work to strengthen our gun laws and protect our communities from tragedies like this."
