@Swoop62 perhaps, but that doesnt mean it would have a negative effect. There's plenty if examples where elimination of these kinds of weapons have resulted in reduced mass shootings.
@Tastyfrzz Then you are talking controlling guns that fire rapidly. Could be true but most are not carried out with that weapon. I read about 2% of mass shootings are committed by the rapid fire rifles.
@Tastyfrzz if they have plans to have a mass shooting then they will have weapons of choice to use. I don't believe they will say I don't have a rifle so not going to do it.
