EL PASO, Texas -- When someone is attacking a woman, she doesn't have to have a weapon to fight back. Self-defense instructor Jaime Guillen said they can use their bare hands.

"If you take your finger and push it into his by having the bones line up, you can have a lot of power here," Guillen said. Guillen teaches women how to defend themselves at JAG Personal Defense.

"If I'm choking you, you can poke me in the eye. If I grab you by your hair you can poke me in the eye,” said Guillen who spent more than 20 years doing special operations work in the military.

Advice like that could come in handy after two recent cases of rape in Las Cruces and 100 cases of sexual assault that have occurred in El Paso this year.

Guillen teaches all kinds of moves like getting away from someone when they pull a knife on you. He said even high heels can be a weapon. He said if someone is trying to grab a woman, she can easily stomp the attacker’s foot or kick the person in the leg wearing her high-heel shoes.

"If someone reaches out and grabs you by the arm to try to kidnap you, you need to go off like a grenade. You don't start begging, because that's the first sign of weakness," he said.

But he says he sometimes has a hard time getting women, especially nurses, to get more aggressive.

"They go, aww, that's kind of mean. You know, that poor dog or whatever. Well then, you're going to get bitten then. And pit bulls tend to grab you by the throat and kill you,” said Guillen. “I have to break you from that so you can defend yourself."

Guillen said about 80 percent of his clients come to him after they have been attacked. He said he has seen his client list double since February, which includes women training for self-defense and training for using a gun. He said typically during the summer, more women come in for self-defense before they leave for college.
