When 17 people were killed in Florida’s Marjory Stoneman Douglas High School on Valentine’s Day by a shooter with an AR-15-style rifle, it was a tipping point for me.

As a hunter and gun owner, I personally am willing to concede points on certain gun-control measures, such as restricting the purchase of military-style semiautomatic rifles with high-capacity magazines and handguns to anyone under the age of 21, or requiring the combination of stricter background check and permitting system for anyone who wants to own what we call an AR-15- style rifle.

That reflects my own opinion and acceptance that gun owners and their advocates should contribute something to the extremely complicated search for solutions to gun violence.

But after the latest school massacre on Friday — 10 people were killed and 10 wounded by a 17-year-old boy in Santa Fe, Texas — we saw some of the same urgent calls to “DO SOMETHING” regarding shootings.

A student survivor of the Florida massacre in February Tweeted that plea, “DO SOMETHING,” while a similar call was sounded by New York’s Gov. Andrew Cuomo.

Addressing President Donald Trump, Cuomo wrote: “You were elected to lead — do something. Your first responsibility is to the people of this country, not the NRA — do something. My heart breaks for the families who have to grieve from this needless violence — DO SOMETHING.”

In this case, do what, exactly?

The most recent psychopath, Dimitrios Pagourtzis, wasn’t wielding a black semiautomatic rifle with a pistol grip, he used a .38-caliber revolver — a six-shooter — and a shotgun when he opened fire on classmates just after 7:30 a.m. The firearms, reports indicate, were taken from the killer’s father, who legally possessed them.

After this latest massacre, is the gun-control movement going to go after .38s and shotguns?

There are countless .38 revolvers and other handgun models in nightstand and desk drawers, behind service counters in businesses and carried when making bank deposits, virtually all possessed by owners who can cite a legitimate need for the measure of protection they provide.

Shotguns? Aside from their numerous sporting uses, from turkey hunting to trap shooting, none other than former Vice President Joe Biden declares a shotgun is really the best way to go when choosing a firearm for security or home defense.

So, aside from issues of accessibility, particularly in the case of children, cries about “doing something” after a crime was committed with a .38 and a shotgun are little more than noise that will go nowhere and solve nothing.

The horrible phenomenon by these terrifyingly determined, almost methodical, teenage boys requires multilayered focus on security in the schools along with mental health assessments and intelligence gathering on possible perpetrators of these acts.

Because the incidents are not going to stop.

Even after the Florida incident in February, a black trench-coated student entered a suburban high school possessing a handgun and shotgun, as well as homemade pipe and pressure cooker bombs, apparently without notice. The so-called bombs could not have been detonated, and reports have not indicated Pagourtzis’ exact movements before he opened fire, but his actions reveal the kind of nightmare scenario that is now possible — indeed should be anticipated — in any school in the country.

Aspects of the shooting actually echoed the massacre at Columbine High School in Colorado in 1999. The two teenage killers in that incident wore trench coats, used shotguns and planted improvised explosives, killing 10 before committing suicide themselves.

What is happening in our society — much of it in suburban America — that we are afflicted with these teen shooters, hollow and numb to the horror and devastation they cause? It’s clear that a twisted fascination with firearms can play a role, but this alone doesn’t explain the hatred and murderous intent they cultivate for their schoolmates — or make them act on it, often after coldly planning for weeks or months.

No measure of gun-control in itself — even if advocates want to broach the subject of outright confiscation — can guarantee the nightmare school shooting will not happen again.

“Do something” in itself is not a solution.
