Paul English was “really affected” by the December 14 shootings at a Newtown, Conn. elementary school that left 20 children and seven adults dead. English, a public health researcher, said he had favored gun control before the killings but had never acted on those beliefs.

“This incident in Connecticut was something that mobilized me to do something else,” English recalled during an interview last week.
