Can't imagine how it must be for Ryan Lanza. Dude got ID'd initially and his name (and Facebook profile pic) plastered on websites and newspapers all over the world. Internet hate machine started systematically demolishing his life, and THEN it turns out it was his autistic younger brother who did the shooting.
Imagine that, sitting in your office with a CNN tab open, and suddenly the newscaster announces the suspect as you. I imagine more than a few liquids would trade places.
It's a tragedy for every possible person involved.
