Tuesday's knife attack at Lone Star College has some students learning to defend against similar situations.
Instructors at Krav Maga in Katy spent Wednesday evening teaching a self-defense class on how to deal with an aggressor wielding a blade.
When it comes to "fight or flight," chief instructor Larry Escher recommends "flight." Run away from the threat if you can make a safe escape.
If not, Escher says, grab a nearby item to use as a weapon. A chair can serve as a shield to fend off an attack.
Escher advises students to focus on the perpetrator, not the blade. Neutralize the person and the knife will no longer be a threat.
Some of his students like to think they would have remembered their training if they had witnessed Tuesday's bloodshed.
"You can never know until you're in one," said Kathryn Scott. "But I have something. I'm not just going to sit there frozen, waiting for whatever happens to me."
