Donald Trump wants to arm teachers with guns

[notimportant1234]

Given all this, it seems the only viable long term course of action in preventing another similar event is to... make sure that the gun never reaches the person, perhaps?
And, since you can't predict who will end up doing this again, maybe it's not a bad idea to minimize the number of people with access to guns.

How many illegal guns that the police and local authorities don't know about would you estimate are in the hands of criminals in our cities?  How would the anti second amendment proponents go about getting those off the streets?

Now you are bringing organized crime in to the topic , nice , what will come next , the drug war ?
