What The Hell Is Up With This Unhinged Idiot Eric Garland?

Glenn Greenwald excoriated Garland over his psychotic stroke session on Twitter, and a tiny bit of working the Google machine points to Eric Garland being fatuous shitstain.  I don't know anything else about him except that he's obviously a C- or D-grade bullshit artist, but now he's internet famous for being a complete fucking buffoon.  Nice job.
