[UPDATE]: The shooter is apparently James W Von Brunn (safe link), and if you Google his name, use the caches; he's a seriously twisted white supremacist who hates everybody sane, or even mildly mad. Give you an idea: he thinks that the Holocaust was faked - but shouldn't have been.
I recommend prayers and good wishes for the security guard that was shot, and his family.- Moe Lane
Lockdown. 2 or 3 people reported to be shot.
