"The first concrete responses to the massacre in Newtown, Conn., began emerging on Tuesday, as state leaders proposed measures to curb gun violence, corporations distanced themselves from an event that has traumatized the nation and the White House pointed to gun control measures that President Obama would champion in the months ahead. The reactions were considerably more broad-based than what had followed previous mass shootings, coming from Republicans as well as Democrats, from gun control advocates and those who have favored gun rights in the past, and even from the corporate and retail worlds. Proponents of stricter controls on firearms said they were cautiously optimistic that, perhaps this time, something concrete and lasting would be enacted... The fallout extended to the corporate world. Cerberus Capital Management announced that it was selling the Freedom Group, which makes the .223 Bushmaster semiautomatic rifle used in the massacre."
