There are indications of some shifts of legislative opinion (at least in the U.S. Senate) about guns in the wake of the Newtown CT shootings. Such changes in position (e.g. by Sens. Warner and Manchin) are good signs, as anything that indicates a weakening of the NRA's grip on many legislators is to be welcomed.
The murder of young children is especially shocking and revolting, and I hope that reactions rooted in normal emotions of revulsion will lead, in this instance, to some change in policy.
