Yes, “good Samaritans” with concealed carry make it unsafe to be a mass shooter.
A similar thing happened in Lancaster, Pennsylvania last year.

Is it just coincidence that mass shootings at schools have gone way up since the passage of gun-free school zone laws in the early 1990s?
Notice the age of the shooters and how it appears to be dropping…as time goes on? Is this the result of a broken home where there’s no longer both a mother and a father guiding their child into adulthood? How many generations down the road are “we” as this problem continues to exacerbate our nation? Are the children of the children even more undisciplined, angry, lacking true love and hope for their future…committing these soulless crimes at an earlier age? As “we” distance ourselves from God, what we’re actually doing is distancing ourselves from, “love The Lord with all your heart, soul, mind and strength and your neighbor as yourselves”. Now look around you, where ever you live in this country, as the evidence of this truth is revealed.
There are children from broken homes, “parents” who have chosen to be “friends” and not true nurturers, homes where the children are raised by the latest on line programming du jour and no order or discipline. Anyone working in school systems knows this first hand. Covid was nice enough to introduce children to a “virtual learning” worthless experience devoid of classroom and school social interaction exasperating the situations. They’ve gone to a virtual world of non emotional play “killing”. There are thousands of teens that no longer play sports or participate in any club activities at all, they have no self esteem or self worth. Some are sent for psychiatric analysis and are medicated with psychotropic drugs or diagnosed with learning disabilities or the ADD variations. There are reality detached children who are taking marching orders from an alternate virtual world. Denying that reality is plain foolish.
An armed society is a polite society.
Mass shootings in schools have gone up precisely because of Biden’s “Gun Free Zone” nonsense. It’s more accurately named a Free Fire Zone for crazy people.
Odds are 50/50 that the hero that stopped the shooting will be arrested and charged. It’s an upside-down world we live in.
Libs here were always demand evidence of good guy with a gun…well were are they now?
If reported at all in the Liberal Media it will be on page 28C between help wanted ads, then quickly forgotten.
1 down 399 to go.
No coincidence at all. “Gun-free zone” signs should be replaced with signs saying “Killers, do as you please zone”
Thanks for popping in. 
This classic video showed there were very few takers for the “Proudly Gun Free” signs for homeowners who supported similar signs for schools.
Gun leeches.
At this point, I think the left realizes the fallacy, but they want only the criminals and police to have guns so their philosophy can be imposed on all of us. They think the overlords will reward them for their loyalty to the struggle. 
Take all of the noise away and that sums it up.
Walk softly and carry a big stick.
Buying guns?
…and all the other weird programs they have put into the schools to detect Mental health problems since the 90’s. All those kids on what is basically speed, and then knowing the entire school system has you down as a kook, they need to talk too to justify their jobs. That must really help their " mental health"…
We’re celebrating that only 3 people were shot and killed? Yay, America!
As opposed to 10, 20, 30 if they had to depend on mall rent-a-cops or the PD? Absolutely.
