Self-defense: More than fighting back

While it's helpful to know ways to protect yourself in an attack, it's also important to be aware of your surroundings and possibly prevent an attack in the first place.

The best defense may be your eyes, ears, and gut.

"When you're walking to your car or walking to a restaurant, don't be on your phone texting, especially if you're in an unknown area. Be alert, keep your chin up, and look at people with good posture," said Wayne Miller, a lead instructor for Krav Maga Worldwide, a martial arts program that focuses on self-defense and fitness.

Miller noted that many would-be attackers are looking for victims who aren't paying attention or who might not be willing to fight back.

It's also important to pay attention to your location, and avoid locations that might appear dangerous or just feel "wrong."

"You don't have to walk down a dark alleyway. And if you have to, bring a friend," said Miller.

"We all have that sixth sense. When talking to survivors, a lot of time they'll say that they have a feeling in their stomach that something was off. You can know all of the great moves, but these moves won't do you any good if you put yourself in a bad situation."

He added that it's OK to be rude if it means you stay safe.

If a person is following too closely behind you, especially in an isolated area, turn to make eye contact or even speak to them.

"Making eye contact shows that you're willing to fight for your safety. These people don't want to fight, they want an easy target," said Miller.

"Something as simple as looking someone in the eye or asking what time it is, or even asking why they're so close to you, goes a long way. If it's a decent individual, they'll create distance and blush or apologize. A would-be attacker will try to negotiate."

If an attack does happens, sometimes the best thing to do is to run away while you can - especially if the attacker seems to be interested in your valuables.

"Your belongings are replaceable. Don't worry about them," said Miller, whose organization has access to footage from thousands of hours of violent crimes through law enforcement agencies in Los Angeles County.

"We've been able to study common attacks. We see women being dragged across the ground because they're trying to hold onto their purse," he said.

"Ditch the purse, or use it was a weapon and throw it at the person. If they want your keys, your phone, your wallet, throw it in one direction and run in the opposite direction.

"Your life is your top priority. Sometimes people forget about that when it comes to their personal belongings," he said.

"You only have one life."
