It is ridiculous how the minds of law makers work. I can not fathom the stupidity, or self-empowered, ideas of these people--make them responsible just like the rest of us. If it is good enough for me, then it is good enough for them is the way I see it. I teach in a deprived and low-income district and we do it without being armed and only one armed security officer a day but we have many violent offenders walking around us everyday so they need to loose their security details too!
As to the ammo, I doubt that we will see anything on the shelves at a reasonable price for some time. Like Klink says, the idea of the US destroying itself is upon us and our enemies only had to invest in our government, take our skilled labor jobs, and send idiotic ideas here like we are seeing on a unprecedented level.
May the Lord keep vigilance over the US and hopefully we won't have to worry about a war with DHS, or any other group.
