Here's more valuable information from Officer Sodimu as posted to the Takoma DC Yahoo Group.
If Someone Tries to Rob You
a.. Don't resist. Give up your property-don't give up your life. b.. Report the crime to the police. Try to describe the attacker accurately. Your actions can help prevent others from becoming victims.
Self defense measures are most effective when applied as preventive steps-avoiding the crime in the first place.
These measures include running away, hiding, screaming, and raising an alarm-remember, more people will respond to someone yelling "Fire" than they will to "Help!"
