“We already know more guns equals more crime and we have an awful raft of mass shootings – gun homicides have spiked in the last couple of years,” he said. “We have a major gun violence problem and expanding Second Amendment protections, greater than they already are, is likely to make it much harder for lawmakers to enact effective laws to reduce gun violence.”
