Dan White had a legitimate beef with Moscone and Milk for the way they had treated him and maneuvered him into resigning from office. Too bad he just didn't walk away, rather than sulk about it and seek revenge. And yup, out of his hot-headed actions we got stuck with Feinstein as Senator for too many years, and the deification of the sodomite Harvey Milk.
Dan White was also a member of a handgun control group that later became Handgun Control Inc and now THE BRADY CENTER.
Guns for me, but not for thee.
