ANTIGO - Wednesday afternoon, an armed man killed 17 people with an AR-15 inside a Florida public school.

School shootings are something people can't predict, but can prepare for.
Two years ago, a shooter attacked Antigo's prom.
That's helped spark a new focus on response to attacks.
The old emergency response plan in many schools called for hiding from shooters.
That's no longer the case.
Schools are now using the ALICE method: alert, lockdown, inform, counter, and evacuate.
Although the situation didn't call for using ALICE at prom, that night is motivation to be ready for a future attack.
"I'll always regret not being there," said Antigo School District Officer Misty Servi.
Servi took the night of Antigo's prom in 2016 off, a decision that has haunted her since.
On April 23, 2016, a former student shot two teenagers with a rifle outside the prom around 11 pm.
Officers immediately shot and killed the shooter, Jakob Wagner, and the victims survived.
"In the back of my head, I always think when is something going to happen, be it at our school or our community," said Servi.
Antigo didn't use the ALICE method to respond to the shooter that night because he wasn't inside the school.
If he was, the training would have called for students and staff to take steps including evacuation.
"[The worst thing you could do is] hide in a corner and do nothing, that's the worst and unfortunately that's all we knew for many years," said Servi.
"It's always surprising and that these things are occurring," said Antigo High School Principal Tom Zamzow.
Zamzow was at the prom right after the shooting. He led police through the school to make sure there was no longer a threat.
"You never would think it would happen to your school," said Zamzow.
Later this month, Zamzow plans to train not only staff, but students too, in the ALICE method.
"You just can't predict, you just have to a plan in place," said Zamzow.
Servi says without a plan, you give the power to the shooter.
"You just feel completely vulnerable. And that's something we don't want our kids to feel anymore," said Servi.
Zamzow now has a program called LEAP: Langlade Emergency Action Plan.
The next meeting is March 3 where they will discuss more funding efforts for ALICE training.
