That's a great article. As with any self defense situation, you have to be prepared for the aftermath as well. Practice it. Recite it as you would practice for a interview.

I'm also a believer in Ayoob's advice. (may be paraphrasing here a bit)

that person(s) attacked me
I was in fear of my life (life of my family)
I will sign a complaint
the evidence is over there.
you will have my full cooperation after i speak to an attorney.
