Typical crap. They clamped down on guns after the Sandy Hook slaughter, and of course to no avail. There was a ban on "assault weapons" for the 21 years prior to Sandy Hook, didn't do a thing. First thing the Assembly does? Retroactively make the rifle used an "assault weapon" by expanding the already-arbitrary definition, ban 11+ capacity magazines, and requiring a permit to buy ammo. I think all private firearms transfers have to go through the State Police as well, or at least pistol transfers.
It doesn't do jack shit when people are being more violent in general. 40 people were murdered in Hartford last year, which I think is some sort of record.
Nearly all murders are single-victim homicides, and handguns are used 19 times more often that rifles. Measures that are at best vaguely orientated to limiting mass shootings will have no statistically noticeable effect on the general crime rate.
Maybe slowing the sales of handguns will help a little with trafficking, although you only need one handgun and a lethal mindset to have a mass shooting.
