Who Condemns Mass Murder, & Who Benefits from It? ..Mainstream Media

It's no co-incidence. The "copycat effect" is real.
It is an effect of such sensationalism in reporting that is fully supported by the leftist gun-grabbers, who have an agenda that they consider so "noble" in its goal that they accept the death of children to attain that goal --- a "gunless society".
Frankly, the only purpose I can see in the "Gun Free School Zone Act" (GFSZA) is to assure the safety of a homicidal maniac for the period of time he spends slaughtering children and teachers. 
It was apparently originally intended as a law to harass lawful gun owners and CCW holders, by making them criminals if they lawfully possesed a gun in a school zone (see the school map of San Francisco). *
But repeated attacks and mass-murders of our children reveal the (at best) "unintended consequences" of that harassment law.
The fact that the gun-grabbers use these attacks to fuel their demagoguery is a clear indication that they now fully accept that slaughter of the innocents, caused by their "gun owner harassment law", even if it was not part of their plan from the start. 
The slaughter of those children is only a tool for them to advance their agenda. They try to blame "lax gun laws", "assault weapons", "the NRA", for the blood that is on their hands. They refuse to consider the repeal of that GFSZA, because it serves their purpose so well. They implicitly accept any "unintended consequence" of the perverse and deadly GFSZA they pushed through under the guise of "school safety", and instead exploit the death and horror they have caused,while blaming innocent gun-owners.

* These “forbidden areas” of otherwise lawful gun possession in San Francisco would follow much the same pattern in any city. Note that it is not recording areas within 1,000 feet of a school ZONE, but apparently only the school BUILDING.
