Some families who lost loved ones in December’s massacre at a Connecticut elementary school say they are very disappointed by the Senate’s defeat of expanded background checks for gun sales and vow to continue their fight. Erica Lafferty is the daughter of Sandy Hook Elementary School principal who was fatally shot as she lunged unarmed at the shooter. Lafferty said, ‘My mom was not scared in the halls of Sandy Hook, they should not be scared to cast a vote to protect millions.’
