HAHAHAHA!! Of all of the things to say to the Police!
"He just confirmed that it was not intended for anybody," Erich Bergendorff said in a telephone interview from his home north of San Diego in Escondido. "It was something that would be used for his own purposes, for self-defense."
Emphasis mine. I am as pro self defense as it gets but WOW! How can someone justify this stuff for self defense and keep a straight face? I mean, I like to sit in my basement and craft the latest defensive loads for my guns just as much as anybody, but can you imagine?
"Hey Earl, didja get yerself some of that there ricin for home defense? I heard its a reeeeeel manstopper!"
It is certainly deadly but it takes days to affect the victim, and there is a serious risk of killing many of the wrong people. It's not like you can just blow it in an attackers face and run them off. You stand as great of a chance of inadvertently killing yourself.
Ricin is a toxin that is made from the castor bean that can kill people dead. As far as toxins go it's about middle of the road in potency, but it's easy to make which makes it an ideal weapon for people like this guy, unless you kill yourself while making it which is entirely possible.
