No, manta49, the logic is that asserting a new law will fix the underlying problems being discussed makes no sense.
Existing laws already address: murder; assault; possession of a firearm by a prohibited person; sale of a firearm to a person who one should reasonably believe to be a prohibited person; carrying of a weapon in a no guns zone.
So, obviously, it isn't the existence or lack of laws, in this case.
It may be improper enforcement by law enforcement agencies and prosecutors; it may be poor sentencing decisions by the judiciary; it may be poor mental health care availability; it may be a societal disconnect from the traditional family and neighborhood model.
But none of those will be changed for the better by new gun control laws.
