3. More guns wouldn't have.

Not sure many would argue that they would have.

Background checks might not have prevented this, or at least incidents like this.

Required safety locks or keeping the guns in a gun locker wouldn't have.

Mandatory training wouldn't have.

You'd require a total ban. Meaning that you'd have to search and seize the handguns. The same Constitution that protects the right to bear arms (of some sort) also protects the right to due process and being free from random searches and seizures.

Part of the problem is opportunity, and that's what some focus on; part is willingness to use the guns to kill, and that's what others focus on.
