KNOXVILLE, Tenn. (WVLT)-- Just down the street from where a rape and aggravted robbery happened at an East Knoxville business is a liquor store run by John Roberts. He tells Local 8 News he once had a similar situation.
"I had a young lady who worked for me and they robbed her at gunpoint," Roberts said.
After that incident, Roberts built a bullet proof glass window that protects him and his employees.
"We've had customers come in here with the intention to do something wrong and they'll turn around and walk out," he said. "That let's us know what we're doing is real good."
Roberts took steps to protect his workers, but what can you do to protect yourself?
A group of people in Knoxville take self defense classes to prepare themselves for anything.
It's called Krav Maga. It's what the Israeli military teaches containing boxing and kickboxing. It's one way Terry Bullman helps men adn women toughen up mentally and physically.
"Most attackers are looking for that weak mark. They're looking for the person who isn't goign to be much of a fight or struggle," Bullman said.
One of the things he trains his students for is what to do if they're ever held at gunpoint.
"If I can get 15 feet away, the chances of them shooting or hitting me is only 5 percent," Bullman said. "Once you learn the things not to do, that's going to help you."
Bullman said your best bet is to fight or run if you're ever in danger.
