In the early 1970s, students in Santa Cruz were given a safety rule:
"Only take rides from cars with a university parking sticker."
Who had that sticker? Ed Kemper had the sticker. Ed fooled the experts.
The rule meant to protect the students is exactly what made him look safe.
Here's the lesson for anyone who teaches self-defence:
* Teach your students that one signal is like a sticker not enough to trust someone.
* Notice what makes you uncomfortable early, and trust it.
* Have your first move decided before you need it.
And it's not just strangers. Most assaults come from someone the person knows. Same strategies over a longer period of time
