March 6 marks the 20th  anniversary of the Connecticut Lottery Corporation massacre in Newington.  That Friday, a 35-year-old employee used a knife and gun to kill four bosses. We condemn the actions of the killer, and express deep sympathy for all the victims and survivors. Within hours,  gun legislation, and metal detectors were discussed. After 20 years, we still have terrorism and violence — workplace, domestic, military, police, government …and yes, Columbine, Sandy Hook and Stoneman Douglas.
