I can't view the link, for some reason. Regardless, I guess your comment is self-explanatory.

I have a personal episode in a similar vein. My departed brother went through a phase in his life when he was something of a "social progressive," for his time. That all changed one day when he was riding his bike in Arlington and some hoodlums drove by and threw a partially consumed coke (aluminum can) at him, which hit him in the side of the head, causing him to crash. (Luckily his helmet saved him from serious injury.) Until then, he had never approved of my interest in weapons, but after that incident he called to ask what type of gun he could discretely carry while on his bike!
I doubt the DA will be so personally proactive. He will have a different "solution."
