The governor's advisers say it's not their job to worry about the Constitution.
In December 2012, after Adam Lanza murdered 20 children and six adults at Sandy Hook Elementary School in Newtown Connecticut, the NRA said: Don't blame guns; blame the mental health system. More than two years later, a Connecticut advisory panel dominated by psychiatrists is prepared to issue a rejoinder: Don't blame the mental health system; blame guns.
What they want is to ban any gun that has a detachable magazine. This is exactly the outcome that the Governor wanted. His hand picked panel, after 2 years of study, decided it's those evil guns. Not the fact that the killer* was a certified nut case. He started his killing spree by murdering his own mother.
*These killers get too much attention and I will not use their names.
