As I wrote 4 days ago, there are no "rules of engagement" in self-defense. These are tools you can use to keep safe, and they work. Most of the time. Your mileage will vary depending on the situation and your skill level. And this is the most important tool of all.
Use your voice. Use it early and often.
This is your single most critical weapon. Assault is a battle of power and control. When you use your voice, you command power. If you've been reading this blog for a while, you've seen this before. If you've taken a Strategic Living self defense class you know the importance of your voice and practiced using it.
Yell direct commands at the assailant. Words like "no" and "stop" and "back off" and "let go" give the message that you are taking your power and using it.
Afterwards, find supportive people to tell. This can include family and friends, crisis clinic hotline or sexual assault advocates, and law enforcement. Your choice, your voice.
